How do i know if java script is decompressing while downloading?

So I created a htaccess file and put this in it and I don't notice a difference.
is there a way to tell in developer tools that its working or not?

For my understanding. What should be faster is the time after the download and when the first scene loads.

Heres my link to test it.

It's annoying Unity used to spit out a warning message in the console, but for some reason they don't anymore. You can check the hearders in the network tab of your browser to see if it's setup correctly. Unfortunately your server does not seem setup correctly. You can see an example I have here: https://forum.unity3d.com/threads/cachedxmlhttprequest-and-htaccess-for-5-6.468396/#post-3062367
