UC Davis is aware of the issue. A recent change in Chrome code uncovered what looks to be an implementation bug in the ISAPI filter: the HTTP protocol requires an empty line tailing the headers and the filter apparently does not send one. Earlier Chrome code and other browsers seem to be more forgiving of this; the new Chrome code enforces the empty line, otherwise throwing the truncation error.
Cf. revision 202927 in http://src.chromium.org/viewvc/chrome/trunk/src/net/http/http_stream_parser.cc?view=log#revHEAD I'm not a Windows developer, so am trying to come up to speed on the APIs to see what could be done with it. I have been in communication with the original developer who suggested, if at all possible, using the .NET CAS client. Tom.
