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

Resource Servlet can't handle query string appended to resource url ------------------------------------------------------------------- Key: RF-11888 URL: https://issues.jboss.org/browse/RF-11888 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: resource handling Affects Versions: 4.1.0.Final Environment: Glassfish 3.1.1 (NO Tomcat)/Mojarra 2.1.3 Chrome browser - Reporter: Brendan Healey Assignee: Lukáš Fryč Priority: Critical 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... 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 in a sensible way. You can set the Cache-Control no-cache header, but I'd need to do this in a way that says "I've just upgraded richfaces, so don't use the cache, issue a request to the server for the resource, but cache the result and use this until the next time".
