Cdn Stuff

I am including the cdn css and js files in my assets. for local directory files the js and css are compressed fine. but it is not working with the cdn files. i want to compress cdn files and make a compress so how it is possible with this.

Excellent Extension: but I have faced two issues

Thanks for the amazing extension.

I have faced two issues: 1- when the Javascript contains "@TODO" as a comment it breaks the whole compressed script file 2- If you have special script/CSS for certain browsers (Conditional using ALT) then the Compression will add them always. Suggestion to create multiple files one for the general scripts/CSS and multiple for the conditional CSS/script

At my server its always pick the css and js from the old cache. Recent changes will not reflect on website. Even after deleting the all cache from the frontend/web/assets/* directory. so please help i need to show recent changes on website.

Yes, the result is cached on some hash. Everything works quickly and optimally for each request.

Will this extension create a cache of the minified resources? Or will It make the compression on every request?
