[jQuery] A problem setting timeout feature in AJAX.

[jQuery] A problem setting timeout feature in AJAX.


Hello,
I have a jquery HTML page which loads a form.
The form has a bunch of settings, but eventually the form gets
submitted using a post command (see below) which returns and HTML
page which was built by a script running on the server.
This works fine, except when the script runs longer than 5 minutes.
The post command just returns nothing.
I tried using the timeout command in the high level page as follows:
$.ajaxSetup({cache: false,
timeout: 18000000 }) ;
But this does not seem to work. Does anyone have a suggestion?
Here is the post command:
$.post('/cgi-bin/tw_lookup_3.cgi', lookupData, function(data){
// $('#results').load( prefix + user_name + "/
TW_LOOKUP_RESULTS.html");
// $('#results a').attr('target','_blank').css
('backgroundColor','#d5e9d7');
var page = $(data).find('input[name=result_dir]').val();
$('#results').load( page + "/TW_LOOKUP_RESULTS.html");
$('#SubmitQuery').attr('disabled',false);
$('#SubmitQuery').val('Submit Query');
$('#SubmitQuery').css('backgroundColor','');
$('#SubmitQuery').css('color','');
},"html");
