[opencms-dev] Configuration of max-age-Header in OpenCms possible?

[Schliemann, Kai]

Hein,

thanks a lot for your answer. I am aware of that option, but I was curious, if there is a setting in OpenCms.
And there is one. See https://documentation.opencms.org/opencms-documentation/caching-in-opencms/static-export/index.html#3.1.4.
One can set exportheaders in opencms-importexport.xml like this:

                  <exportheaders>
                                 <header>cache-control:mag-age=2629743830</header><!-- one month -->
                </exportheaders>

Best regards
Kai

If you use Apache you can set DateExpiresHeaders like in
https://gtmetrix.com/serve-static-assets-with-an-efficient-cache-policy.html
or somewhere included in your httpd.conf.

Hi list,

OpenCms seems to set the max-age header to 1 day per default.
For SEO reasons we want to change the value at least for static resources like images, css and js files.
Background info: https://web.dev/uses-long-cache-ttl/

There are several places In the source code where the DateExpiresHeader is set: https://github.com/alkacon/opencms-core/search?q=setDateExpiresHeader

I wonder, if there Is a possibility to change that setting in a config file?

Thanks for your help.

Best regards
Kai
