Closed as program error.
| Error description
When a request header is sent and the value length for one of
the parms exceeds 8190 the request will fail the 1st time with a
400 bad parm when request is on port 9080. The reason is the
buffer size is hardcoded at 8190 and if the request exceeds this
it wil lexpand the buffer by 8190 bytes. On the 1st request, thi
s expansion fails and causes a 400 error. On subsequent request,
the default size is set to 16380 and will work until a size
exceeds 16380 and the buffer needs to expand again. Local fixProblem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server developers *
* creating request header fields greater *
* than 10K. *
****************************************************************
* PROBLEM DESCRIPTION: WebSphere fails to handle request *
* header fields greater than 10K for *
* webservers that permit header fields *
* greater than 8190 bytes. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
WebSphere defaulted to the apache limit of 8190 bytes
for a request header field (10K total for all headers).
This limitation would be encountered when dispatching
requests via the plugins and using a webserver other
than an apache based webserver. When using the internal
webserver, to process requests, after 8190 bytes were sent,
the initial 8190 bytes were not being sent to the
webcontainer. Problem conclusion
To honor the limits for request header fields and total
request headers, WebSphere will expand the buffer capacity on
an as needed basis to accomodate large header fields. This
expansion will allow WebSphere to handle any request header
field on any supported webserver implementation. Temporary fixComments
