Hi,

my website is very slow to load. I have analyzed the problem with FireBug Firefox extension, and found that the .js files loaded by PrimeFaces are up to 3 seconds to load, individually. Specifically, jquery.js, jquery-ui.js, menu.js, core.js and some accompanying CSS files are the reason for this.

It seems the files are never stored in the browser cache.

I am using

Code: Select all

<context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>    
    <param-value>Production</param-value>
</context-param>
... so that is not the problem.

I'm using Glassfish 3.0.1 with PrimeFaces 2.2 RC2.

Has anyone else encountered this problem?

Thanks.

Anyone ? It seems the browser always reloads these files. They are never cached.

Hi and thanks for your response.

I'm having a hard time deriving a concrete solution from these threads.

I'm using Apache with mod_proxy in front of my Glassfish 3. Perhaps I should let it cache these resources instead?

Also, can you post a concrete example of your servlet filter code ?

Thanks.

As JSF 2.0 APIs are loading the resources, this questions is more related to the JSF impl not PrimeFaces library.

in case someone is looking for an answer to this problem, after upgrading to mojarra-2.0.3 glassfish handled caching all the resources for me.. with mojarra-2.0.2 it did not.

Hi,

You are correct. I just upgraded, and now everything is cached.

Is there a way to control the caching? Will it result in problems when I change some of the source files?

Thanks.

I you think Mojarra 2.0.3 automatically handle caching, can you please post the HTTP response headers of a typical static source?

It's just 304 NOT MODIFIED

304 NOT MODIFIED means your browser in contacting the server (and spending considerable time in establishing the connection) about the modified information, it is not the proper caching anyway.
