Closed as program error.

Error description
Intermittently, customers may experience unexplained 404 'Not
Found' errors at the browser when using the v4 HTTP plugin
for IHS on z/OS.  A plugin trace of the failure will show that
a request was sent to the J2EE transport, but the connection
was reset due to a timer popping (generally, the keep-alive
timer).  This causes the request to be resent.  The newly
sent request will appear garbled in the trace, because the code
attempts to translate it again from EBCDIC to ASCII.
