Hi.
I’m newcommer in web applications and also I’m amateur in english word!!! 
I have a form that send an Ajax request to the server to create a backup. In some case it may take 2 hours to complete and regretfully I face an ‘Internal server error 500’, despite the server is in progress. How can I force my form to stay more for answer from server???
Hi
‘Internal server error 500’ usually means Internal server error 500 
and I think you have to configure server, not client.
what server do you use?
YES!!!
Thank you for your attention. My problem solved. And as you said it was related to server…
I am using linux with PHP 5.3.3 and set_time_limit(300); was the answer of my problem, and NOT ajax Timeout.
