[richfaces-issues] [JBoss JIRA] Commented: (RF-7452) org.ajax4jsf.DEFAULT_EXPIRE needs to override 'Pragma' header

org.ajax4jsf.DEFAULT_EXPIRE needs to override 'Pragma' header ------------------------------------------------------------- Key: RF-7452 URL: https://jira.jboss.org/jira/browse/RF-7452 Project: RichFaces Issue Type: Bug Components: browser compatibility Affects Versions: 3.3.1 Reporter: Richard Kennard Assignee: Nick Belaevski Fix For: 3.3.2.CR1 Attachments: addressbook-faces.war The flag org.ajax4jsf.DEFAULT_EXPIRE, which defaults to 86400, is meant to set client-side expiry for static resources (see RF-2506 and RF-4212). This is a great idea but it is incorrectly implemented. The problem is browsers differ on what they consider as the 'expires header'. For correct operation, a combination of 'Pragma', 'Cache-Control' and 'Expires' is needed. At the moment the code is setting 'Pragma: No-cache', which means expiry does not work on Firefox. If you use Firebug, you can see all the resources are reloaded every page. This is what RichFaces currently sets as its headers, by default: Pragma: No-cache Cache-Control: max-age=86400 Expires: Fri, 26 Jun 2009 22:32:50 GMT This is what it should set: Pragma: Cache-Control: max-age=86400 Expires: Fri, 26 Jun 2009 22:32:50 GMT
