So that looks good. Unless anyone has any objections I will post 
it to RAMBO as a feature request.

In future, I think a proper mapping function (probably using PARSE) 
should be created, and path-thru would use that instead of REPLACE, 
but until then I think this is a very good and cheap fix.

OK, I posted a RAMBO ticket for this.

I don't know, but "?" can be used as a wildcard on *nix, so I think 
it's not supported in filenames (but I've no real experience with 
*nix)

Kru, as I understood on unix, filenames could contain any ascii characters 
0-255, but using characters such as "?" would confuse a lot of programs, 
so it was avoided. I don't know what the situation is these days.. 
Maybe they are more restrictive of allowed filenames.

Thanks Sunanda, just skipping through it now... as I expected, a 
complex fudge. :)

about time.  It's a nightmare trying to clean spyware off ....

Pekr: You can let that person know that MS is a member of the w3c, 
last I heard.

Who uses XSL, SMIL or VRML?  And the PNG trick privides marginally 
better alpha PNG support -- but only 32-bit and not in CSS.  Look, 
there is a standard document format -- XHTML.  There is a standard 
way to make it look nice on multiple mediums -- CSS.  And a standard 
way to add images -- PNG.  As the major web browser, IE limits these 
standards (CSS + PNG) through limited support -- that sucks.

I know - ppl did not let him argue anymore ... he was not able to 
provide valid arguments for MS not taking browser enhancements back 
to older Win versions. Producing IE 7 for XP only is not a solution 
...

The trick for me is to reconcile the she-bang line, not only for 
different servers and OSs *but* also with different scripting languages. 
 Using one she-bang line on the test machine and a different one 
on a live server is full of potential errors, regardless of the language. 
On apache/windows the following line being enabled: "ScriptInterpreterSource 
registry" tells apache/windows to find an association in the registry. 
Well, there is no rebol/core installation procedure to do it, and 
the registry entry appears to be different from windows 98/IIS, and 
I haven't been able to figure it out. I need to be able to run scripts 
from rebol, python and perl on this machine *and* to be able to upload 
any of them to a unix/linux server. so ..... I installed rebol and 
user.r in c:\usr\bin, installed python at   d:\python23 *and* copied 
python.exe to c:\usr\bin. So far rebol and python are both working 
using #!/usr/bin/rebol and #!/usr/bin/python respectively as the 
she-bang lines (with ScriptInterperterSource turned off). I will 
later try that with perl and see what happens. If that works, then 
I have a solution. However,  it seems to me that the rebol installation 
should provide proper registry entries to by-pass the she-bang line 
as perl and python do.

Using one she-bang line on the test machine and a different one on 
a live server is full of potential errors,
That's true.

But using the *same* shebang in a collaberative development forces 
all developers to have the same setup. 


We sorted that in REBOL.org by having the custom uploader change 
the shebang to be correct for the upload destination.

you can upload a test-script with that shebang and call it from rebol 
as part of the upload.

as in linux you have a http.conf file to edit

you have a tool named apache monitor to start apache serv and to 
stop it or restart it :)

There would be no collaboration on this machine between rebol programmers. 
Two programmers, one using rebol and python (me), the other using 
perl. And of course we are using the same setup, because all scripts 
are being uploaded to any of a number of linux or sun system servers, 
all of which use the same convention: #!/usr/bin/[interpreter]. I 
fully understand Sunanda's approach, but in the case of rebol.org, 
there are many programmers working from multiple machines in multiple 
OSs. I think the the c:\usr\bin approach will work fine for our humble 
endeavor.

Having said that, I want to eventually study Sunanda's approach more, 
because I want to eventually set up a rebol-based system for uploading 
that will handle she-bangs *and* dependencies.

BTW: Rebol.org seems to be progressing very well. If progress continues, 
I envision something as sophisticated (and hopefully easier to use) 
as CPAN. Keep up the good work.

Tim: A general purpose uploader would be very useful.

I'll drop you some notes privately on some ideas for what it should/could 
do.

Sunanda: I quote you from another forum: Tim: A general purpose uploader 
would be very useful. I'll drop you some notes privately on some 
ideas for what it should/could do.....Looking forward to it! My idea 
is of a cgi upload script that for any cgi script, first checks a 
web site and compares timedate stamps, checking to make sure that 
dependencies are current and if not, makes them also available for 
upload. BTW: Some time ago on the rebol ML,

there was reference to an enhanced FTP module. Does that ring a bell? 
<grin> or was that you?

i use two mirror-directories. one is a full mirror of the website. 
in the second fresh uplods are stored. i put them there by comparing 
the upload-files with the ones in the full mirror. then i scp to 
the website.

Does anyone have an idea how one can get the timezone a particular 
server is on (in an automated way) ? eg. What timezone is www.lexicon.net 
in ?

The reason I wanted to know was because I'd like exists-thru? to 
be able to calculate the age of a remote document, so it can compare 
with the locally cached version.

how does 'info? work .. a similar way?

we're a pretty tame lot here ... good job Terry is around to wake 
us up now and then

OUTLINE OF SCAPEGOATING PSYCHO-DYNAMICS

In scapegoating, feelings of guilt, aggression, blame and suffering 
are transferred away from a person or group so as to fulfill an unconscious 
drive to resolve or avoid such bad feelings. This is done by the 
displacement of responsibility and blame to another who serves as 
a target for blame both for the scapegoater and his supporters. The 
scapegoating process can be understood as an example of the Drama 
Triangle concept [Karpman, 1968].
http://www.scapegoat.demon.co.uk/

(I hope this is the right group to post this in.)

I have a problem, when reading a file on another computer thru a 
shared drive. I'm sitting on a Windows client, and the file is on 
a UNIX server. First time I read the file, it's ok. Then if the file 
is updated on the UNIX server, I still get the old version on the 
client.

I've tried the read-thru/update command, but it doesn't solve the 
problem. Maybe read-thru/update doesn't work with shared drives? 
My code looks like this:

read-thru/update %/u/adv71-20/data/invoice.txt

Any ideas?

(It's possible to distribute a sync from the server to the client, 
and then I'll get the new version of the file. But I'll like to be 
able to get the new version from the client.)

It seems, my problem is only with Win98. Even a normal read works 
on Win2000 and WinXP.
And then you tell me: DON'T use Win98, right? ;-)

I want a report to give me a good overview about the year, current 
month etc. AWStats looks good in this. I like the visits and sample 
trials reports of wusage. Shows how people browse your site.


Clicks-to-result must be as low as possible. Simple to install, configure 
and use.

Geomol, READ-THRU is mainly for urls. READ-THRU file   operates almost 
just like  READ file. Anyway, I recommend just use READ, if you want 
the latest contents.  If it is true what you say, then it looks like 
there is some caching by Win98 or the driver for the shared drive. 
(So, outside rebol's control). However, perhaps you could force a 
sync by "touching" the file you are interested in reading first. 
By "touching" I mean use set-modes to change one of the file-modes, 
eg:

>> print mold get-modes %a 'file-modes

[creation-date access-date modification-date owner-write archived 
hidden system]
>> set-modes %afile [archived: true]
>> set-modes %afile [archived: false]
>> get-modes %afile 'archived
== false

Good suggestions, Anton! Yes, I'm pretty sure, it's outside REBOL's 
control, as I sometimes see strenge behaviour (for example regarding 
file locking) in other programs. The intra-network, I'm doing those 
things in, is a combined Win98-Win2000-WinXP network with a few UNIX 
servers present. The way, we share drives, is the standard Windows 
way using the SMB protocol (using Samba on the UNIX servers). I've 
for a long time suggested, that they do it the UNIX way and install 
NFS clients on the PCs in stead. I tried to install some ProNFS client 
yesterday, but couldn't get it to work (probably because of some 
lame Windows authentification, maybe also encrypted passwords).


It could be interesting to see, if the cache problem dissappear when 
using NFS.

Q for javascript/CSS guru.


How to change the font weigth of an <input type="text"> field with 
Javascript ?


I have a function called on OnChange() event that check the value 
and I want to display the field in Bold if value > 0, or normal if 
value = 0

I downloaded a page from a web site, but it will not display.  Could 
this have something to do with frames? What must I do to get this 
file to display?

Got a link?

Here is the script I used to download the files.  

rebol []

page: read http://militarygetsaved.tripod.com/id23.htm

links: []

parse page [some [thru {<A HREF="} copy temp to {"} (append links 
temp)] to end]

foreach link links [

Hm... I'm trying to parse a webpage and strip all HTML tags from 
it but my approach isn't work.  Grr!

I have a problem with HTTPS over a proxy. I'm using REBOL/Command 
2.5.6.3.1, that came with our SDK. This version first need the HTTPS 
protocol to be activated using this code:


net-utils/net-install HTTPS make system/schemes/http/handler [] 443

system/schemes/https: make system/schemes/https [user-agent: reform 
["REBOL" system/product system/version]]

I activated trace by typing: trace/net on

Our proxy is set up ok, as I can read the internet with a browser 
using it (both HTTP and HTTPS).
Now if I in REBOL do this:

>> s: read https://webservices.rki.dk

I get:

URL Parse: none none webservices.rki.dk none none none
Net-log: ["Opening" "ssl" "for" "HTTPS"]
connecting to: webservices.rki.dk
Net-log: {CONNECT webservices.rki.dk:443 HTTP/1.1
Host: webservices.rki.dk:443

}
Net-log: "HTTP/1.0 200 Connection established"
Net-log: {GET https://webservices.rki.dk:443/ HTTP/1.0
Accept: */*
Connection: close
User-Agent: REBOL Command 2.5.6.3.1
Host: webservices.rki.dk:443
}
Net-log: none

** User Error: Error.  Target url: https://webservices.rki.dk:443/ 
could not be
retrieved.  Server response: none
** Near: s: read https://webservices.rki.dk

I see two possibilities:

1) The proxy is not supporting tunneling, as required by reading 
the REBOL documentation http://www.rebol.com/docs/ssl.html
2) There's a bug in the REBOL/Command, I'm using.

Any ideas would be very much appreciated!

I guess a web browser works ok?

And I'm sure, I'm going through the proxy with the browser, as I 
tried a wrong TCP/IP port and got a proxy error. With the rigth port, 
it works ok.

And if I try with a wrong TCP/IP port configuration (like I did with 
the browser test), I get this:

>> s: read http://www.rebol.com
URL Parse: none none www.rebol.com none none none
Net-log: ["Opening" "tcp" "for" "HTTP"]
connecting to: www.rebol.com
** Access Error: Cannot connect to 193.3.239.91
** Where: open-proto
** Near: s: read http://www.rebol.com

So I am going through the proxy with REBOL.

it's a library and also command line utlity for doing web stuff.

curl is a command line tool for transferring files with URL syntax, 
supporting FTP, FTPS, HTTP, HTTPS, GOPHER, TELNET, DICT, FILE and 
LDAP. Curl supports HTTPS certificates, HTTP POST, HTTP PUT, FTP 
uploading, HTTP form based upload, proxies, cookies, user+password 
authentication (Basic, Digest, NTLM, Negotiate, kerberos...), file 
transfer resume, proxy tunneling and a busload of other useful tricks.

Carl: I have to check that at work tomorrow (I didn't set it up). 
We're testing on a proxy, and another one is at a customer, where 
it doesn't work either. The customer is the norwegian oil company 
Statoil, and we have their words, that it supports "tunnelling", 
but I'm sceptical as usual. ;-)

Completely different.  I think we discussed www.curl.com on the mailing 
list many years ago.  Someone was saying that they had a proposition 
for View to do a job, but it ended up being done by Curl.

I also tried reading a https page using command and squid, and couldn't 
get it to work.

Out customer Statoil use a hardware proxy from NetApp called NetCache, 
and they have the same problem.
http://www.netapp.com/products/netcache/netcache_family.html

Tunnelling is supported according to their specs: http://www.netapp.com/products/software/software_specs.html

Graham: Do you know, how tunnelling works with squid? (I'm not a 
proxy expert in any way.) Does it have to be turned on or something 
in the config file?

Seems like SSL Tunnelling with squid is on by default on certain 
ports using the CONNECT method:

http://www.squid-cache.org/mail-archive/squid-users/200210/0295.html

Our customer was monitoring the trafik and could see, that nothing 
happened after the CONNECT, so maybe the problem is, that REBOL doesn't 
continue after the CONNECT!? As I understand it, the CONNECT method 
is used to establish a connection between the two computers (client 
and server), and then the proxy simple let the communication continue 
without touching it (allowing SSL encryption and the like). REBOL 
can make the connection, but fail to communicate afterwards. (My 
guess.)

Geomol - there is nothing like "connect". If you have a free bit 
of a free time, I suggest you to download Winpcap and Ethereal - 
they are both free and you get cool network monitoring tool. You 
can learn a lot ...

I started it Tuesday 11:26 with a problem regarding HTTPS over a 
proxy.

Graham: I've done Ethereal monitoring with our test proxy, and after 
the "HTTP/1.0 200 Connection established" reply from the proxy, there's 
a line from my computer (running REBOL) to the proxy with the text 
"Continuation or non-HTTP traffic". After that, the proxy reply with 
a [FIN, ACK]. If that "continuation" holds the information from my 
REBOL application to go to the server in the other end, it may be 
a proxy problem!?

I notice a bug in the CONNECT request from REBOL to the proxy. Ethereal 
reports:

[Dissector bug, protocol HTTP: "Request Version" - "http.request.version" 
invalid length: -32 (proto.c:2104)]
!?

I'm having some problems with the rebol example webserv.r   I've 
installed it on a computer at home and a computer here at work. It 
works fine at home, but here there appears to be problems with the 
path of the script. The log file is places several places (where 
the webserv.r script is located and severel places inside the www 
path), and there are problems accessing rebol scripts inside :[  
]: - apparently also because of problems with the path. Very wierd 
behaviour. Any help appriciated.

I've solved the problem with HTTPS thru a proxy. The problem is, 
that the commands to the proxy is sent with only a newline in the 
end of each line. If I replace the newlines with carriage-return 
newline ("^M^/"), it works. Within the SDK, the problem is in the 
file "source/prot-http.r".

Geomol, that is a known bug in ssl, see RAMBO #3532, it is interesting 
to know that it affects HTTPS with proxy

Off topic here, but what do you have to do to create an external 
link on  a web page so that a new browser instance loads. Do you 
need some javascript on the page?

just add target="_blank" in the <a> tag

<a href=http://www.rebol.comtarget=_blank>Rebol</a>  ?

is that the same for the action of a form ?

it should if the action is redirection to another page using the 
<a> tag.  But I'd need to look it up to be certain.

Graham: I'm not sure, if the copyright on prot-http.r prevent me 
from posting it, but I can tell you, what I added to it. My work-around 
consists of 2 extra lines after line 46, which in my version is:

append http-packet "^/"

My extra lines are:

replace/all http-packet "^/" "^M^/"
remove back tail http-packet	; Because a newline will be added.


It's not a nice solution, but it works. A better way would be to 
open the port with a /with refinement and CRLF. See RAMBO #3532.

Does anyone know away to automate the checking of a website that 
requires https, authentication and probably cookies. I basically 
want an application to log into my ebank account and extract some 
information.

When I try the samples.  they all fire off the download, etc.  install 
seems to work, except that I always end up with red x, and nothing 
ever runs.  Just wondered whether anyone ever figured out what was 
up with that, or whether there was any momentum at all with rebol 
plug-in.  I'd probably rather have an active-x/progid sort of affair, 
but talk about a can of worms.  I've never done it, but looked into 
it.  seems like it may not be such a big step, though, if there's 
been success with browser plugin.  This is all sort of an aside. 
 I didn't really have anything particular in mind, except as maybe 
an Ajax alternative.

There isn't normally a problem with IE6.

I'm not expecting any new plug-in releases until LNS is out and other 
builds are done. Don't know about momentum, but I'm using it for 
a project and it's pretty darn handy if you ask me.

I've been in awe of it since I got it working.  IE has been my primary 
platform for a long time now.  Spent quite a bit of time building 
a working asynchronous http client with IE's xmlhttp, but now am 
wondering why I bothered.  Rebol makes me nervous and excited about 
the implications.

that is fantastic.  I'm starting to shake a little.  beyond all expectations. 
 talk about power to the people. . .  I'm off to do some crazy prototype. 
 I'll post a link when I get something wild cooking.

I think it is a matter of "Safe for Scripting" which would need to 
be a safer subset of the full view.

I guess I should build a .r that is restricted to this safe subset. 
 I think I basically want to accomplish a web page that is obfuscated 
peer to peer instant messaging.  I see rim as an example.  Is there 
anything about rim that could not be accomplished within a safe-for-scripting 
subset?

It seems, a call to net-log failed, and that was the cause of the 
problem. It's because NetCache has extra header-lines, that e.g. 
Squid doesn't have. See RAMBO 3638.

Anyone know a list of web anonymisers that I can try ? All the ones 
I've tried have failed to connect from here in Australia.

Is there any easy way to create an app using a View front-end, but 
manipulate data on a webserver backend?  Would a normal method be 
to write the View frontend, then use cgi for the backend?

I was thinking of writing a webapp, but I'd rather have View handle 
the GUI lifting.

So Rugby runs as a server on its own port and I'd have to poke a 
hole in my firewall?

Rebol kills me.  The deeper you look, the more you find.  You wonder 
why more people aren't aware of it.  After playing with Rugby a bit, 
I don't think I'll write another personal cgi app again.

Note also that rugby runs as a daemon so you would usually have to 
run your own web server.

I'm already running a webserver, so it's no big deal.  If the connections 
are encrypted, I don't mind having the extra port open.

The only problem I have noted is that occasionally my application 
goes crazy memory wise, and cpu jumps to max .. which fortunately 
can only be 50% on a hyperthreaded pentium 4 cpu :) 

I think the problem may be with Rebol and ODBC, and will try to port 
to Postgresql and use Dockimbels driver instead of odbc.

But I don't think there's a comparable version of encap ?

Some weeks in real time or some weeks in  a test environment.

I log every action and message of my servers, so that I can play 
them again in a shorter time, but in the same sequence.

Weeks in real time.  I had not thought of logging every action .. 
though I do run a log for some things.

Yes, the information has been encoded on the main site with a compression 
format (French) for which you don't have a decompression utility.

Not. His website changed a couple of times. Last known (to me) working

But that is broken now.

or maybe I misread your preference -- Magic is more like a HTML-generating

what do you mean by notation? :-) I already said that I preferred 
Temple way to go. Simply put - I am not designer, my designer is 
not a coder. So I want him to freely produce his "magic ui wonders",using

maybe slower aproach - html with comment sections, parsed by rebol, 
replaced by engine ...
