World: r3wp

Search engines like to index things a user can see.

Thye get suspicious of anything that appears to be built just for 
the.....No surprising given how much they have been gamed by SERPS 
spammers.

Having a human-readable site map has the same effect as a crawler 
page *and* taks you a long way towards having a site that is navigable 
by people under any conditions.

The google-approved method of doing a crawler page is to use what 
they call a sitemap:

Someone could easily modify Carl's site-checker to emit a google 
sitemap:

How to reset variables sent from a form using POST method without 
redirecting into new page? I mean how to prevent, that using reload 
will resend the values again. I usualy just set location to other 
page after processing, but now I have case when I need to display 
informations without change of the location. I think I've seen somewhere 
that it's possible using http response, but cannot find it:(

I'm not sure of a single http header designed for this purpose.  
There are cache controls, but how long to set them for?  Or etags/if-none-match, 
but would that prevent the browser's resend warning?  Or a token 
value in your form that expires after one submission, though also 
would not prevent the resend warning.  Or sessions?

never mind, I will do it in the way I do it usually, that means redirect 
to other page after processing of the upload

if there is nothing, you could id  the page and block further  replies 
 with the same id.

Volker, that is etags...

i guess i am clueless and beter  stop spamming. what is etags?^^

compare the post values to the last sent post values?

Etags should work like this: client requests a resource, server returns 
resource and etag header.  Client again requests resource, but this 
time sends if-none-match header with etag value and server can then 
decide whether to process the request or send 304 not changed.  I 
haven't explored this much so don't know how well it's supported 
-- I'm not sure how appropriate the solution is, but would involve 
the least server activity.

ah

the problem is, that if you are posting large file, it's not too 
good, as all file is first uploaded again and than you can decide, 
if you want it to store for example. I though I sow something, but 
maybe it was just a fata morgana, I thing, that the best is the redirect. 
My problem is, that I'm trying to connect on database, which was 
not designed by me, so there is no crypted id for the data I upload, 
just incremental integer, which I don't want to use, as I would give 
chance to everybody go thru the data just inserting other numbers. 
I have to take a risk, modify the original database adding ne column 
with crypted id and redirect to the uploaded data using this id. 
And hope, that I will find and modifie all places, where is this 
database used:(

reload resends post data? I thought that to resend post data you 
have to press submit button :-)

nevertheless now I understand why I sometimes get double posts with 
some chat boards :-)

It depends on which browser you are using -- they have different 
behaviours in this area.

Hmm, im using http-tools , I login to a page which sends a cookie 
which I then have to send back everytime, however the cookie seems 
to expire after one post :/

anyone user http-tools off of rebol.org ?

REBOL's POST , GET etc really need re-working -- for an IT aware 
language posting to websites id ridicoulously hard

is*

charles, welcome to reality !  In theory rebol supports many protocols 
but in practice the support is incomplete and it has been incomplete 
for a long time. check rebol.org, there are several patches for cookies 
support

I wrote http-tools, but haven't used it for years.

you normally need to send the cookie each time ... that's what browsers 
do

yes, I am sending it each time, but for some reason it seems to only 
like the first request, after that it expires , or something else 
is going wrong ... Id really like to see a client with transparent 
support for cookies

are you getting a redirect from the second page ... that is followed 
without the cookie

oldes did something on transparent support ..

so did I .. but that was long ago.

Yes, I did, and if you scroll a little bit up, you can find the link 
easilly - it's in big yellow block of text:) And I agree, that it 
would be good to have cookies support directly in Rebol, as my cookies-daemon 
is relly hard hack I cannot be sure that it would not rewrite some 
future http protocol updates

Has anyone tried to solve at least some basic anti-spam form protection? 
I mean - those numbers/letters you have to rewrite to your form field, 
in order to be processed? Will it work with rebface at least, if 
my Linux server has no X-Win installed?

I want to do some small post-card system for my friend. He can't 
program much and adapted small php solution, but that solution is 
so basic, that it even does not randomize postcard number in presented 
link ... so you can cange your url and get access to someone's else 
message. That is imo unacceptable.

What I really like is www.view-card.com system. It is able to embedd 
images directly into email's body (not an attachement), but I found 
out, that most freemails has html email displaying turned off by 
default ....

had anyone done an email address validation according to rfc 2822? 
Well, I mean email adress part? Our to-email "whatever-stupidity-you-write-here423423423-rebol-considers-being-an-meail@{{}}}]//" 
is kind of funny :-)

I thought datatypes should be usefull, and there is exactly precise 
description of what is, and what is not email, so how Rebol can simplify 
it so much?

Not quite an email address validator, but the REBOL.org uses an email 
address spotter [contributed by Andrew Martin] to find and obsfucate 
email addresses in ML messages, etc.

You could use the same basic parse patterns to identify / validate 
email addresses. 

I haven't checked RFC 822 in detail, so it is likely that Andrew's 
code is more liberal than the actual spec, but it could be a starter.
Would you like a copy of the function?

yes, of course ... you can send it to my mail address, or point me 
to some link ...

thanks a lot :-)

I wrote an email validator .. which works by doing an smtp challenge.

http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=email-check.r

it's probably a reason why my spam has increased on gmail :(

Note to Sunada ...  licence (english) and license (american) spellings 
appear on the same page :)

graham, you really should remove the addresses from there, especially 
those which are rebol.com related....

You don't see them unless you're logged in!

As Graham says, the addresses are munged on REBOL.org unless you 
are a logged-on member of the Library. That doesn't stop a spammer 
grabbing them, but it does reduce the risk considerably.
**
Thanks for the spelling correction!

I (finally) got around to fixing the license/licence typos. Thanks 
again Graham.

If you spot any other typos on REBOL.org, please report them in the 
Library group.

Incidently, I tend to use US english for webpages and British english 
for program code (variables, comments etc), so my code is littered 
with duplicate spellings: color/colour etc,

Hi,

I need another short advice :-)

do you prefer:


- directly accessible menu menu: http://www.creactive.cz/work/xidys/online/

or


- initially collapsed menu: http://www.creactive.cz/work/xidys/xidys_web_hp.jpg

   - with mouse-over effect: http://www.creactive.cz/work/xidys/xidys_web_hp2.jpg

   - and after clicking an item: http://www.creactive.cz/work/xidys/xidys_web_sec.jpg

(dis)advantages to both:


According to company working on our website, there is something like 
slight barrier, when user needs to click, and wait where the click 
does take him/her. According to them, users prefer scrolling. OTOH 
the menu can get long, and e.g. e-shop direct icon is not visible 
(nor is last section), and there is no easy other place, where to 
put such an icon (direct link).

thanks a lot :-)
-pekr-

Have you seen, what Jakob Nielsen say about menus?
http://www.useit.com/alertbox/20011209.html
http://www.useit.com/alertbox/20001112.html

There are many good advise in his alertbox: http://www.useit.com/alertbox/

ok, thanks for links!

I definitely prefer all the info being visible on the page.

Expecting people to play hide and seek is good in games and some 
styles of websites. But if you are trying to make your site (and 
therefore your company's information) easily available, then don't 
hide links in any way.

OK ... what about the screen height problem? More so with new wide-screen 
LCDs? It is like 800pixels, minus Start bar, minus browser (app bar 
+ menu + toolbar + tabs), which usually lets you with something like 
500 - 600 pixels ... not all those menu will be visible then ... 
but ppl can scroll :-)

I prefere the directly accessible menu as well

ok, so far that seems to be option of circa 60% of ppl I asked :-) 
40% prefer partially collapsed aproach, and noone prefers pop-up 
menus :-)

No who says VID is missing menu? :-)
