How can I allow one client to run multiple simultaneous PHP requests?
I've been googling a lot. I tried session_write_close() at the top of my PHP script.
I tried to edit the httpd.conf but nothing bites.
What should I do?

Have you tried jQuery? Is there a particular reason you want to close the session? – CragMonkey Feb 15 '15 at 16:53

Sounds like you're looking to perform an asynchronous request (AJAX), and jQuery is useful for this.
Check out the jQuery.ajax() documentation.
There are plenty of tutorials online to help you get started with jQuery, and this SO post discusses how to make Multiple ajax calls at same time.
Edit: Since you clarified in your comments that:
- You are already using jQuery but are running into challenges with the server allowing multiple simultaneous connections.
- You also indicated that you already tried adding missing values to httpd.conf and restarted your Apache server.
If adding missing settings to httpd.conf doesn't work and you have also checked that they are not already included in httpd.conf through, perhaps, httpd-mpm.conf.
Your OP indicated that you have tried resolving the session conflicts using session_write_close(), but perhaps the additional requests are getting discarded/ignored rather than queued.
You could try replacing the default file-based session handler with one that calls a database, which should eliminate the problem of conflicts that arise when two processes attempt to read the same session file at the same time. This article (Saving PHP's Session data to a database) seems to cover it pretty well.

I just want to configure my Apache to allow multiple connection per client. – user1878980 Feb 15 '15 at 17:02

I already use ajax, but it doesn't help because Apache doesn't allow multiple simultaneous connections for a client. – user1878980 Feb 15 '15 at 17:06

1yes I did, but I cant find where to edit these options for apache. I'm looking in httpd.conf but the options aren't there, so I tried to add them, but it doesn't work. – user1878980 Feb 15 '15 at 17:08

Is your httpd.conf including *httpd-mpm.conf* ? Those settings may exist there instead. – CragMonkey Feb 15 '15 at 17:30

It works if I run the script simultaneously from different browsers (or different browser sessions) which solves my issue for now. Big thanks @Cragmonkey – user1878980 Feb 15 '15 at 19:13
