Ok – if you or your customers / family / friends / pets / household gadgets have installed ISA Server 2004 SP2 and are experiencing this “502 http filter blocked” response for sites that work without SP2, please call PSS and provide:
– ISAInfo (http://isatools.org/isainfo/isainfo.zip)
– network captures at the ISA external interface
We’re trying to assess the scope of the problem and we can’t do that without hard data.
NOTE: I would like to obtain a collection of URLs that produce the 502 filter blocked error. Note that this error should be specific to HTTP HEADER NOT SUPPORTED errors. You can email me your sites that generated the HTTP HEADER NOT SUPPORTED error at firstname.lastname@example.org.
