Data Capture Callout CGIs

Hi There,
Im trying to learn how datacapture cgi callouts work in teamsite and im having some trouble. I was trying to follow the example given in the formspublisher's developers guide and i noticed this is how they used the callout tag:

< callout url="/iw-bin/iw_cgi_wrapper.cgi/example_datacapture_callout.ipl/
options.txt" label="Weather Patterns" window-features="width=320, height=200, resizable=yes,toolbar=no,scrollbars=yes"/>

1)I am not able to find any documentation on the iw_cgi_wrapper.cgi file or any other cgi file that resides in C:\Program Files\Interwoven\TeamSite\httpd\iw-bin and i am not able to view it using any text editor. Could somebody tell me how i can view these files.

2) If i use the callout tag in this way:
< callout url="/iw-bin/example_datacapture_callout.ipl"> is it still considered a valid cgi callout. The reason i ask is because i was able to modify the .ipl file to do exactly what it did before.

I know some of these topics were covered in another post: http://devnet.interwoven.com/forums_vb/showthread.php?t=17388&forumid=50&highlight=difference

but i am still having some trouble with this topic.

I'm not sure where it is documented, nor whether it still works the way it originally did - but iw_cgi_wrapper.cgi was intended to allow for impersonation - that is, to make the CGI program behave as if it was being executed by the user who is logged into TeamSite as opposed to the service/process owner that runs TeamSite.

With 6.7.1 there's now the iwutild service/process and an iwutild.cfg file - as well as some specific settings that might need to be placed within the [authentication] section of the iw.cfg.

In either case - the iw_cgi_wrapper.cgi is a binary program - so you cannot look at the code (unless Interwoven happens to provide it to you - which is unlikely).

If you can get the CGI to do what you want without using iw_cgi_wrapper.cgi - I recommend doing so as it is one less level of abstraction / obfuscation.

Thanks for the reply ghoti but just to confirm, what i am doing within my .ipl file is still considered datacapture cgi callout right? It uses the Teamsite::CGI_Lite library.

If you're using the callout or cgi-callout element in your DCT - then yes, it is a datacapture cgi callout - regardless of whether you use TeamSite::CGI_lite, CGI, or any other module.
