Multiple simultaneous HTTP requests are handled by multiple CGI jobs.Similar
to telnet. One user, one session, one job.

For each of the 5 CGI jobs, the current user is QTMHHTP1.

I'm not sure what you mean about making the CGI persistent. So that the
program stays running within the job? That would mean extensive recoding
and how would it help with multiple simultaneous http requests?

We have 2 other similar web services running in production. They also have
5 CGI jobs running but only 2 ever seem to get used.

You're right that the main multi-threaded HTTP server job routes CGI
requests to "available" CGI Jobs, normally. But you also have the option of
coding for persistent CGI. See the manual for examples.

Hi,

If my CGI program crashes, I thought that the nexavailable CGI job would

be

used for further http requests. Apparently not, they return with an error
http 500.
Is there anything that can be done to change this behaviour?

My http.conf :
StartCGI 5
#HotBackup Off

So I have 2 groups of 5 CGI jobs each running program QZSRCGI. The first
job remains in MSGW condition. I believe that if another request was made
from another client while the first job was still occupied, then the next
available CGI job would be used.

What condition needs to be met so that the request uses the instances 2

to

5 of my server jobs?
