So, I call up the webmaster of that website, and tell them their webserver is broken, and leave it at that? If it works without being proxied up, and fails through a proxy, what would I tell him/her to do ... to fix the issue? Since it's ASPX could it be the code itself (which I'm considering -- if the code is called one way, you don't get header info, if it's called wit the isFrame=1 then you do get proper header)... >>> Henrik Nordstrom <henrik@xxxxxxxxxxxxxxxxxxx> 08/12/09 7:01 PM >>> ons 2009-08-12 klockan 13:54 -0500 skrev Rob Poe: > We're using Squid 3.0STABLE18 (just upgraded to see if it would fix this problem - it did not).
