Error description
When using the v5 HTTP Plugin with the IBM HTTP Server,
customers may periodically experience 404 'Servlet Host not
Found' errors returned to the browser when accessing their
web applications.  This will be accompanied by messages in the
servant region joblog of the requested application such as:
.
 Trace: 2003/09/29 17:56:30.154 01 t=ACE5A8 c=26.2 key=P8
   Description: Log Boss/390 Error

   from filename: ./bborjtr.cpp
   at line: 812
   error message: BBOO0223I no private server port header
.
Subsequently, the servant region will attempt to use a value of
-1 for the port assignment on the request, which will not be
valid.

Web container does not detect the private header, $WSSP, that
the Plugin inserted into the request.  It ends up using -1
for the request port and failing the request. This error trace
is issued:
Trace: 2003/09/29 17:56:30.154 01 t=ACE5A8 c=26.2 key=P8
  Description: Log Boss/390 Error
  from filename: ./bborjtr.cpp
  at line: 812
  error message: BBOO0223I no private server port header
The web contianer did not find the header because it is looking
for $wssp, but the HTTP transport incorrectly lowercased it to
$Wssp. This error could cause any private header to not be
detected.
Problem conclusion
The HTTP Transport had a parsing/lowercasing error when only one
character of a HTTP header line is read into the input buffer.
The remaining portion of the header is read in but one character
is not lowercased. The processing error has been corrected.
