Error description
Intermittently, customers may experience unexplained 404 'Not
Found' errors at the browser when using the v5 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.

Problem conclusion
The plugin code is modified to avoid double EBCDIC-to-ASCII
translation.   The code is also modified to add missing
EBCDIC-to-ASCII translation for the Expect: 100-Continue
header and ASCII-to-EBCDIC translation for the response
to the header.
