Currently we have a few users that are running some business related reports from an external website. The users are successfully running "small" reports where there isn't alot of data to be returned and complied into the report.
The users try to run reports that would be considered "large", the session times out. Logging on the proxy server returns the following:
1460 This operation returned because the timeout period has expired.
My assumption is the backend webserver they are pulled these from doesn't send any communication while it is compiling the report and the session is dropped. If the users run this report from home, it works fine.
It seems to be that the main issue is the third party that is generating these reports has an application that doesn't fit "industry" standards for keeping sessions open. From what I have read, it seems ISA by default has a 120 second timeout value.
My question is, is there anything I could do on our end to help allow this process to work properly through the ISA proxy? If the default timeout is changed, wouldn't that change for all web traffic? Any information would be appreciated.
