How to setup an expiry date or a maximum age in the HTTP headers for static resources to instruct the browser to load previously downloaded resources from local disk rather than over the network ?
I have installed Microcache on my Production ModxCloud, but it didn't help.
I use this tool to check my Website performance:

And the results are pretty bad for my Modx Websites regarding leverage browser caching for the cacheable resources. I get "(expiration not specified)" for all the css, js, jpg and png resources.
How could I improve this ?
Thank you for your help.
