A customer is using HTTPS to access a website running on IIS 5, and Squid is fairly consistently hitting this assertion error while they attempt to access the site. Squid seems to be failing on a different request than the request for the problematic site, though - the request in this traceback is for urs.microsoft.com rather than the original website:
2011/03/07 10:29:11| assertion failed: client_side.cc:3756: "bodyPipe != NULL"
(we have some local changes, so the line number 3756 might not exactly match the line in the stock cache_cf.cc file)
The stack backtrace is:
