The Cache exlusion 'helps' with www.mix999.com but does not seem to help with delta.com. The errors recieved on each are differnt.... It appears to be an issue within the Web Proxy Filter that the Delta Error is coming up (I may be off base on this statement). I suggest you contact PSS to file a ticket. If it proves to be a bug in SP2 I would think they would not charge for support on it.. You may want to verify that prior to opening though.
New to the forums!
We installed the SP2 and now receive this same error for at least two sites, delta.com and neucoinc.com when users attempt to use them. I have been reading through the posts here and we have just implemented the cache-disable from above. Will post results when we continue testing.

Hi Chuck, There have been some reports of issues with the new compression filter introduced in SP2. Try disabling this filter – in ISA mmc – under Configuration -> Add-ins -> Compression filter. Do this on all machines in the array. Then restart the ISA server control service on each machine in turn. Jacob
Glad to see I'm not going crazy. I ran across the same 502 proxy error this afternoon. Had the owner of a company who ran up against this breathing down my back this afternoon. I also discovered the workaround by googling for Delta and then clicking the longer Delta home page URL. However I had left the office shortly after that so I wonder if this owner tried booking a flight. Sure I'm going to get the 20 questions treatment next week if he did.
Error Code: 502 Proxy Error. The HTTP request includes a non-supported header. Contact your ISA Server administrator. (12156) IP Address: 188.8.131.52 Date: 19/02/2006 10:44:18 Server: ******* Source: proxy
Have tried disabling the compression filter as suggested to no effect - I think that is related to the similar web filter error rather than this proxy error.

That just gets you the home page. The unsupported header error occurs when you try to log in or search for a flight. None of the other fixes pustulated work either (like disabling the compression filter). It looks like I have to roll back the service pack.
