Hi,

recently while doing some updates/overhauls on my site UI (css and jquery mostly) I found that there were cases where my edits would not be seen by the end user until they initiated a ctrl + f5 to clear browser cache. The site I am updating is using CRM and has persist files set in the settings.

Could this be a cause for the cache issue I am facing? Is it just a case of incrementing the version when the 'persist files' is set to true in order to insure all end users will see a properly updated version of my site?

Thanks

If you are changing css anywhere on your site - then yes you will need to increment the counter - otherwise the system will not update its cache of the combined css modules.

Basically the system works by merging javascript files and css files into  single file - so that there is only one http request for each type of file each page load.   The name of these merged files are unique ... but as the name itself doesnt ever change - your web browser will continue to use the old cached version unless you hit ctl-f5.

The alternative is to increment the Current Host Version number in the Client Resource Manage - this have the same effect as ctl-f5 - since it forces the browser to reload the files and bypass their cache.

If you have already set long duration cache headers at the browser then you can't do this from the server.
