PQ60675: GENERIC "*.JSP" RULECAUSING PROBLEMS FOR THE CUSTOMER. CUSTOMER ADDS A NEW APPLICATION TO WAS A PLUGIN-CFG.XML, DOES NOT WORK.

APAR status
Closed as program error.

Error description
The rule *.jsp is causing problems for customers.  When the
customer calls his app using port 80 it fails, works using 9080
Problem with URI matching.
Local fix
The "*.jsp" rule is causing problems for customers.  Customer
can add an application, can not access on port 80 but is
successful for port 9080 due to URI matching.
Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server version 4       *
*                 users of the webserver plugins.              *
****************************************************************
* PROBLEM DESCRIPTION: The plugin would perform a first match  *
*                      of the incoming request parameters with *
*                      the routing rules.  The generic rule    *
*                      used by the samples of *.jsp would      *
*                      prematurely cause the route             *
*                      determination to end and could result   *
*                      in the plugin routing to the incorrect  *
*                      application server.                     *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The plugin matching algorithm is a first match algorithm and
could result in the request being sent to an unwanted app
server for jsp requests when the sample apps are installed.
Problem conclusion
The plugin now uses a best match algorithm where uri matching
is scored and depending on what rule has the highest score
the plugin will pick the best route for the request.  A
better score is obtained by larger numbers of characters for
a rule matching the inbound request.
