Seam 2.0.2 SP1 + Richfaces 3.2.0 Performance Issues

[dax1]

Environment:

1. Jboss AS 4.2.3 GA
2. Seam 2.0.2 SP1
3. Richfaces 3.2.0

For a page that has menu panel, tab panel, rich panel, et. al. we see a lot of requests for Javascript, CSS, etc being made from the generated page.

The requests are like:

We have enabled mod-gzip and mod-expires but we notice his does not get applied on the a4j requests.

Any help will be appreciated.

thanks.

Try adding the following to your web.xml which will make RichFaces download all the css and js as big cache-able files.

        <context-param>
                <param-name>org.richfaces.LoadStyleStrategy</param-name>
                <param-value>ALL</param-value>
        </context-param>

        <context-param>
                <param-name>org.richfaces.LoadScriptStrategy</param-name>
                <param-value>ALL</param-value>
        </context-param>

Thanks for your input, it worked great. Now though I the requests have been now reduced to just a 3 requests for the JS and CSS i.e.

But I still can't figure out why these JS and CSS are not getting cached even though mod_expires is enabled on my Apache.

Any further thoughts will be greatly appreciated.

Pragma: no-cache

Id say this is your problem, somewhere along the way this is getting added. The first step is to find out if it is jboss or IBM HTTP Server that is causing adding these headers.

Pragma: no-cache

came out ?
