Re: Apache directive syntax

Many thanks

You say the initial program must only be called once. I'm not sure if that
is possible. I guess it would work as long as the initial program doesn't
start the persistence and is just there to give you a link to the second
program

That is exactly how it works. The initial program has no output - it
simply calls the CGI program (indirectly) and that deals with persistence.
As I have said, it all works fine with the original HTTP server.

Persistent CGI isn't complex once you understand it, but I just don't
understand how to configure Apache to replicate the original HTTP server.

The other difference is that I have to distinguish between the initial
program which calls my CGI program (indirectly) and that CGI program, as,
rather obviously, the initial program must only be called once.

is possible. I guess it would work as long as the initial program doesn't
start the persistence and is just there to give you a link to the second
program. Here is how persistent CGI works with Apache on the IBM I to the
best of my recollection.

Open program /cgibin/mycgi.pgm
The very first output must be Accept-HT:myhandle
Myhandle has to be unique. It is what tells apache to leave this program
open, and how to get back to this instance of the program.
You output the rest of the page as normal. In there is a link that posts
to /cgibin/mycgi.pgm/myhandle/
When you submit that post, the same instance of mycgi.pgm is called. If
you need multiple programs, you would need to call them from the first
program.

I have had it working before as a proof of concept, but like you, I was
extremely frustrated with how complex it was to make it work. In the end it
was decided that rewriting everything in PHP and using stored procedures
was easier than trying to tack persistent cgi over our existing screens and
workflow.
