The process owner depends on the httpd config, right?

yes; and if you use SuExec the process owner becomes the script owner 
(i.e. your user id), but SuExec is tricky business.

is it possible to extract/change a cookie from the site a plugin 
is working in?


  I have embedded an app within an IIS served web site.  I must make 
  the reblet interact with the site's cookie, so it follows the rest 
  of the site's status when relaunched (browsing to/from the app from 
  other pages restarts the rebol app).

google "javascript cookies tutorial" and use rebol to call javascript 
to get the cookies

thanks this will get me going   :-)

Hi,  question for the webheads.


   In short.  Can a form call a cgi action that processes data but doesn't 
   output any Content-type

(or anything for that matter) without the browser status coming up 
with "waiting for reply".


   I've got a client that wants a form for requesting more info, but 
   they want to leave the user on

the same screen, so I thought I could have a %process.cgi that takes 
the data and plays with it

and then have an intrinsic  onsubmit=alert(...)  to inform the user 
that the request has been submitted.

The %process.cgi doesn't 
print "Content-type ..."


it doesn't print anything, as I was hoping to leave the same browser 
screen up.

Am I living in lalaland?


Should the %process.cgi just redirect back to the original page with?


print "location: /original.html^/content-type: text/html^/"  or is 
that deprecated now?  It works under my test heads, Cheyenne and 
nonIE browser, but is there a bigger better way?  Or do I tell the 
client that the browser needs a new page and I can add a back link 
(not preferred).

Thanks for listening

You could try sending back a 204 response.
Means "no content" in the response.
No idea what a webserver would do with that.
A 205 might work too.

why should not the user leave the form? should a user be able to 
send it multiple times?

if you need to rely on JS, you could do an xmlhttp request...

I'm popping up an Alert...

This is a client request, I'm looking at options.  Thanks for the 
hints.

The form comes with a note about Javascript...so far anyway.  I'm 
showing off the

print "location: " umm, redirect, to them right now as we speak.

I'll reinform them of the potential problems of having this type 
of form on their page.

And thanks to %blog.r's abuse? code, I should be able to stop most 
of the potential harm...but I'm still reiterating this to the client.

Hello, I need to send multipart/form-data to a server for uploading 
a file from the console. I've been googling and searching the script 
archive, to no avail. Can anyone help?

Daniel;  Try http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=cgi.r
 for some code.

And http://www.rebol.net/cookbook/recipes/0026.htmlfor a REBOL sample 
solution  and then wait for the rest of the forum members to pipe 
up with 'bigger better' solutions, and they will.  :)

Thanks for the help. The recipe from the rebol cookbook show you 
how to upload a file provided the server runs a rebol script too. 
The server I'm uploading a file to doesn't. It expects multipart/form-data. 
Maybe the %cgi.r by Cal Dixon provides a solution. I'll investigate 
further. More hints will be appreciated, as well...

Try this ML thread http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-message.r?m=rmlKVSQ
and some notes by Sunanda on CGI 'safety' 

http://www.rebol.org/cgi-bin/cgiwrap/rebol/art-display-article.r?article=x60

In that ML thread, the request was to handle a multipart upload on 
the server side (in rebol). I need to perform a multipart upload 
on the client side (in rebol). As for the seconde link, unfortunately 
I get "Article x60 is no longer available ". Any idea?

In other words, the rebol script has to send values to a form on 
the server issuing something like that in the header: Content-Type: 
multipart/form-data; boundary=----------6l5Xq9lJYPaaypknAH8Des etc. 
Surely someone has done this before (I hope)...

My bad. http://www.rebol.org/cgi-bin/cgiwrap/rebol/art-display-article.r?article=x60w
 but unfortunately this article skips over the info for multipart/form.

Try http://www.rebol.org/cgi-bin/cgiwrap/rebol/ml-display-thread.r?m=rmlRDSC


But to be honest, I've been waiting for Graham or Dockimbel to notice 
the conversation.   My exposure to this sequence is purely "little 
think cut'n'paste" from the cookbook, since I'm REBOL in, REBOL out 
for the website I run.  :)

Oldes' script looks like it should do the job.

this is an article I wrote in 2003 hacking the http protocol to do 
this too http://www.compkarori.com/vanilla/display/HTTP+file+uploading

Thanks, Graham, you hit the right spot. Like you say in your article, 
"Read/Custom sets the port to lines modes, and there is no clean 
way to change this to binary for binary uploads". But that's exactly 
what I need. Which script by Oldes are you referring to? Where can 
I find it? Are you saying that his is doing the job?

The last ML entry I mentioned has the reference to Olde's script. 
 rmlRDSC  If it does the job of tweaking the lines mode?  Haven't 
looked.

I don't know if it helps, but I did write a web server stress test 
that did a http upload of hundreds of images in Rebol that year.. 
but the scripts are long lost.

I used a variant of the http-tools.r script, composed the correct 
header, and then insert the headers, and then switched the port to 
binary before inserting the payload

Ok, I'll try to hack the http-tools.r, see if I can get anything 
done. I saw a script written in python claiming to do multipart uploads, 
but I hope I can get it working in Rebol, which for me is always 
first choice.

Thanks everybody. I'll keep you posted.

what are you doing? still uploading binary? then use open/insert/close 
and change port to binary if it is open

hmm, does open/custom do that. i hope..

i guess i am on the wrong track..

I played with Oldes script a bit, didn't get far. I think there's 
no other option than follow Graham's advice and delve in the http 
scheme. I had hoped to find something in the script archive, oh well... 
I saw that even in the Ruby and Python community there's some confusion 
on how to achieve multipart form submissions with CGI. (Python default 
http library also uses  "application/x-www-form-urlencoded" and not 
""multipart/form-data", but there's a library called HTTPFileUploader 
that does the job). Last time I tried to hack the http scheme I wasn't 
so succesful. This time, if I need help, I'll ask for help.

do you need to write binary, or a multipart?could be multipart can 
use base64. then its somewhat bigger, but has no problems with text-mode. 
could even be that multipart of email works the same. in that case 
there is 'build-attach-body.

The script should be able to post a multipart form as described in 
rfc1867. It should be able to post a number of fields, for example: 
Content-Disposition: form-data; name="userid", and finally it should 
be able to upload a file in binary data.

Graham described what needs to be done (I used a variant of the http-tools.r 
script, composed the correct header, and then insert the headers, 
and then switched the port to binary before inserting the payload). 
Only it's a little a bit above my capacities. In other words, I'll 
need two weeks to do it, if I ever manage it.

Graham, I'm a big fan of http-tools.r (I believe you wrote it,right?). 
I used it in my DYNdns client that I wrote in Rebol. I realized only 
recently that some of the functionality was built-in.(Basic authenticaion 
with read/custom). Grrrr... if only you hadn't thrown those upload 
scripts away :)

Daniel, I wrote http-tools.r before there was a read/custom .. that's 
how old the script is!

Yeah, I remember some tips you contributed to the rebolzine on posting 
to web forms, way back... Anyway, I think I won't tinker with the 
http scheme, kinda dpressing thought, especially since I have great 
hopes to achieve what I need using curl and the shell capability 
of Rebol. Let curl do that work, afte r all, that's what' it's meant 
to do best.

I found the script .. written in 2002.

Undocumented .. but basically it took a directory of jpegs and zip 
files and uploaded them to a java based webserver that required custom 
headers

Great, can I see it?

And the good news is: curl does it flawlessly. I just saved myself 
two weeks of headaches. I am a reboller, but not a purist, if I find 
a better tool to do something, that's cool with me.

Sent.

Received. Thanks, indeed.

Anyone know the answer to this one? 

I have a cgi script that sends an email out. The problem is that 
I want to send to an address that has the same domain name as the 
website but whose mail server is not located there (It's an Exchange 
Server). Any other address works fine as expected. I think it has 
to do with the mx records but, the weird thing is that if I generate 
an email via php, it goes through. Therefore I'm thinking Rebol can 
do it too. 

I've used set-net  for the smtp server and have set it a different 
server completely but still no go.
And I'm in the process of having the MX records changed.

what is the trace/net say?

Oh, Haven't tried that. I'll see.

usually PHP uses the sendmail command directly, not SMTP, so it can't 
be compared unfortunately (ie the fact tha php can send mails does 
not guarantee that rebol can). but, you could use CALL and call sendmail 
directly too if there is no other option.
