PQ67809: PLUGIN SPECFIC MATCHING DOES NOT INCORPORATE VIRTUAL HOST SCORE

 A fix is available

4.0.6: WebSphere Application Server Version 4.0 Fix Pack 6



APAR status
Closed as program error.

Error description
The plugin used a scoring method during URI resolution to
determine if a URL is intended for Websphere.  This scoring
counts the number of characters that match between a URI entry
in the plugin-cfg.xml and the client's URL.
.
The plugin-cfg entry that has the most matching characters is
used to continue with URL routing.   The plugin scores Virtual
hosts and URI separate,  therefore a VirtualHost/URI combination
that is an appropriate match may get bypassed.
Local fix
Play around with generic URL rules
Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server version 4.0     *
*                 users of the webserver plugins.              *
****************************************************************
* PROBLEM DESCRIPTION: The hostname was not being used in      *
*                      the scoring that is done to determine   *
*                      which route in the plugin config file   *
*                      best matches the given request.         *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The hostname not being included in the scoring algorithm
could result in a route that would be a best match
for a request not getting selected leading to an undesired
route for the request.
Problem conclusion
The VirtualHost rules were included in the scoring algorithm
so that route matching could find the most specific route
match for a given request.
