Leverage browser caching for the adobe analytics satellite.js files.



Can anyone please help me to how can we cache these js files to improve site performance.

No browser caching for few JS files:All the JS files received from the host http://assets.adobedtm.com, do not have any caching applied to them. I do not think we can do anything since we are accessing them over network from the server.

Here is the list of DTM files, DTM team needs to come up with an approach to handle caching for these files.


Kindly refer the screenshot and do advice me how to approach the possibilities.

Have you checked to make sure your browser has caching enabled? Cache Control is set to 0 for Satellite files so the browser should check the last modified date from the server and only download if it's later than the one it has. Right now my browser is reading satellite files from cache as they were modified a few days ago.
