> 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
