Hi Johannes,

Whenever me make changes in js, css, jsp and deploy on App Server... One usually has to clear cache on all browsers to see the new changes. Same is the case when a jquery-plugin jar or grid-plugin jar is migrated from lower version to higher version.

My application is deployed on Websphere server and used by more than 40k+ users across the globe. We cannot possibly ask the end users to delete cache from their browsers whenever a new release of the application is deployed. In IE, it is even more painful as you need to physically delete the files.

1. Is there any solution (by any means necessary) to this problem ?

2. Is this only the case with jquery or with other js libraries like prototype, yui, mootools / dojo also.

I think there are 2 solutions.

1.) Add a time stamp parameter after every resource

myscript.js?time=20110426093600

this forces a reload. But with this way you disable caching.

2.) rename your scripts myscript-0.x.js instead of myscript.js

This problem is independent from your javascript lib.

Point number 2 sounds good for the application specific js, css files. Thanks.

However the library issue would still remain. i.e. whenever a jquery plugin jar or jquery grid jar is migrated, it should not cause javascript errors due to cache not cleared. Please fix the same for future versions.

I apply this for the most common resources.
