Hi,

I am running an ISA 2006 SP1 server with Web proxy filter.
Occasionally, a request will come in through the proxy and the destination site would be down and unresponsive (in a sniff, it does not respond to three SYN requests).
This site is also configured as "Bypass" in the ISA configuration.

In this case, a 504 error would be returned to the originator after a very long period of time, I saw 63 seconds in one case. is there any way to set this timeout?

Thanks

Well yeah, the error is 504 and I will see it in the monitoring tab. other than that why would there be another error?

Hi Sulimanw,

"the destination site would be down and unresponsive (in a sniff, it does not respond to three SYN requests)."

I will try to explain again:
I am dealing with a site that is actually down, I have no complaints towards the website owner, nor do I care why his site is down.
My internal users are making requests to this site, however I have configured this site to by Bypassed by ISA's web proxy filter.
In this case, I don't seem to have any setting for a timeout of such request. ISA is taking a lot of time to close the connection and give up on it. like I said, in a sniff I can immediately see that the site does not respond to three SYN Requests, so why does ISA take so much time in closing the connection and returning an error?
