LinuxQuestions.org - Ajax Timeout in different Network

I have searched all over the net about this problem and a bunch came out but they did not provide a definite solution for the problem.
I saw this post http://www.linuxquestions.org/questi...18#post5373818 but there was no solution provided. I posted it here because there might be a configuration in there server needed, and yes the server is in Linux OS, CentOS to be exact.

The issue is that, I have Web Application, this is already in a public DNS, that generates report and then exports this as Excel file. When I try this in my network I was able to get the excel file with 5-6 minutes of execution of the Ajax.

But when my client execute this, in a different geography as where I am, the ajax request will expire (timeout) for 30 seconds ONLY! I dont understand why only 30 seconds but when I execute this it will reach up to 6 minutes.

in my php.ini, I already set this up:

Code:

 max_execution_time = 0

 max_input_time = 0

and in my php, I put this up in the start of the script:

PHP Code:




    set_time_limit(0);

in my ajax request, BTW I am using EXTJS 4:

Code:

  Ext.Ajax.request({

      url: 'validurl',

      params: {},

      method: "POST",

      waitMsg: "Exporting data. Please wait....",

      timeout: 900000,

  ......

  ......

What/Where could be the issue?application?network?server? how do I resolve this?

Thank you.
