* PROBLEM DESCRIPTION: Performance of Web components deployed  *
*                      in a J2EE server is not adequate when   *

* RECOMMENDATION:                                              *
****************************************************************
The performance was poor because of the callbacks from the J2EE
server to the Plug-In for writes, reads, and getting cookie
values.
Problem conclusion
Changes were made to the V4.0.1 Plug-In to avoid callbacks. This
model does not support POST data size of more than 11MB.

The following COMPID is affected by these changes:
 5655A9800 R401 on z/OS andOS/390.
The code changes are stored in CMVC under defects
