[richfaces-issues] [JBoss JIRA] (RF-11888) Resource Servlet can't handle query string appended to resource url

[Brendan Healey (JIRA)]

Brendan Healey updated RF-11888:
--------------------------------

       Priority: Critical  (was: Major)
    Description: 
A custom resource handler (http://blogs.oracle.com/rlubke/entry/jsf_2_0_new_feature)
can be used to append a version string (i.e. ?v=23) to a resource url to force a
browser to refresh a resource rather than use any cached version.

At present any appending of a version string causes a 404 response status, for example:

Request URL:
https://localhost:8181/MyApp/org.richfaces.resources/javax.faces.resource/org.richfaces.staticResource/4.1.0.Final/PackedCompressed/blueSky/packed/packed.css?v=23

Removing the url parameter makes it work ok. As you can see I have resourceMapping
enabled.

This is essential to cause a browser to issue a request to the server if a static
resource is held in a browser cache and is not expired, but you've upgraded the
richfaces version. You have to have a way to invalidate the cache, and I'm not
seeing how this can be done.

This is useful as a last resort strategy, perhaps after a major redeployment, and
also in the event that there are other problems setting useful ETag and Last-Modified
http response headers.
