Our website is Megento Enterprise based- e-commerce.
I’m working on a request for a developer to specify caching headers/or do it myself if possible/or have server provider assist with this.
In which file caching headers need to be specified?
Per Google recommendations ea. header needs to have Expires or Cache-Control (Expires preferred) and Last-Modified or Etag. Can someone provide an example with both specified with correct syntax?
I’m thinking to set all css and js files to 24 hours to start
Static images- to 30 days
3-rd party widgets - 24 hours?
What about Google Analytics, Google Tag Manager and re-marketing tags- can they be set to over 24 hours?
Thank you for any clarification that can be provided.
