Good day

I've got an ISA 2004 server that is used for internet access only, when I try to connecto to a certain URL through the ISA, I get the following error:

Technical Information (for support personnel)
Error Code: 502 Proxy Error. The HTTP request includes a non-supported header. Contact your ISA Server administrator. (12156)
IP Address: 69.25.56.150
Date: 29/06/06 10:12:34 AM
Server: ismid01
Source: proxy

Where can I see what the Header is that the URL is using and how do I allow this Header to go through ISA

Any Help would be appreciated

Thx
Floris

I've seen that same error on my server when I enabled compression after loading SP2.

Disabling the compression for request to the external network, in the General Configuration settings, seems to have resolved my issues.

Check the Alerts tab under the monitoring section in ISA Server Management console.

You should see the exact reason for the header being rejected.
