Joe Bohn commented on GERONIMO-4722:
------------------------------------
It appears that we were too aggressive in the application of the XSSXSRFFilter.
There is no strong reason that this should be applied to the welcome
application which has a context-root of "/'. Combine that with the filter URL
pattern of "/*" registered for the filter on the welcome application and nearly
every url is inspected. It seems we can remove this filter from welcome.
Refer to this thread for more details:
