Extra parameters injected into portlet request
----------------------------------------------

         Key: PB-13
         URL: http://issues.apache.org/jira/browse/PB-13
     Project: Portals Bridges
        Type: Bug
    Reporter: James Schopp
    Priority: Minor


The extra parameters "_spage", "_sorig", and "_kra" get added to the portlet 
request  For some applications (IBM WebFacing, for example), these un-expected 
parameters cause issues. Allthough they may be necessary for the Struts bridge, 
they should be filtered out by the time the request reaches the actual portlet.

I have solved this by creating a new RequestWrapper that filters these 
parameters (configurable in portlet.xml). The wrapper is created (and wrapped 
around the real request) in my ServletContextProvider.

Ate, this may be something you consider app-specific, but it's pretty 
configurable, and there is no overhead if you do not configure any parameters 
to be filtered. So, it's more flexibility, with no drawbacks (and it get's it 
out of my code and into yours ;-)
