the website is using a jquery autocomplete and when you type in after 5 minutes in the customer's network you get a login screen.   then it triggers and error in the fetch javascript.

 

 If most people call the website, it does not time out for 30 minutes.  In the web.config I have the time out for 30 minutes.

I have a customer using a computer inside their company, if they dont do anything on the website for 5 minutes and then try to key in in the autocomplete, I get a system login screen and then the javascript error on the control

I ran tests on 3 different machines. two inside my company and on on my personal computer.  I tested the page at 5,10,15 and 20 minutes and it did not time out

I tested it on FF and IE with the same results.  I have know idea, when the customer runs the website inside their companies network it times out at 5 minutes

our website is an asp.net page and resides on a windows server.  I have tested other website on my server and they do not time out at 5 minutes.
