Optimal value for org.ajax4jsf.DEFAULT_EXPIRE

[kchintoju]

All the RichFaces resources served from the web-app come with default Expires Header of 24 hours(for browser caching). Which is controlled by context param "org.ajax4jsf.DEFAULT_EXPIRE" with default value for "86400".

In production I'm planning increase the cache time to a month or even an year. As I assume these js files contain none of developer code and the url of these resources will change when we upgrade to a newer version.

Am I thinking wrong here (just wanted to confirm, is there anything in these JS files which will change in each build) and is it advisable to do this ?

Example resource:
http://localhost/our-web-app/a4j/g/3_3_2.SR1/org/ajax4jsf/framework.pack.js

Hi,

That's ok to change it to a bigger time. Note that this setting will affect rich:paint2D and a4j:mediaOutput as well.

Thanks for the info. Didn't know it would affect the output of those tags as well. Anyway I'm not worried as we don't use those tags.
