[opencms-dev] Setting Browser Cache directives

[Alexander Kandzior]

The is because of the browser cache, many browsers don't even ask the server
again (at last for a day or so) once the have the page in the cache. 

The wayout of this is having an "expires" header set on the page.

You could try to put a "timeout" cache directive (property) to your
templates or one of the incuded elements. OpenCms should then send and
"expired" header set to the next expiration of the timeout, which should
solve the issue. 

Best Regards,
Alex.
