[Oisf-users] Detect problem with http_header

http_raw_header does not work.  Removing 0d 0a does not work.  In
fact, searching for just "attachment" in http_header does not work.
Stats show the stream is properly processed and all packets are
accounted for.  No one else is having issues with http_header in
responses?  I verified that the latest git code behaves like the code
we have in production.
