Hi Ozzy,
Can you do a browser test to the VIP and use developer tools in the browser and look for the "Content-Encoding" header in the HTTP response? You should see that header along with a value of gzip/deflate/ etc. You can also use a curl statement to test/verify as well:
curl -I -H "Accept-Encoding: gzip, deflate, br" https://yourwebsite.com
Additionally, you can try to compare file sizes of the content your are trying to access by using adjusting the "Accept-Encoding" headers: some examples below:
With compression: curl -H "Accept-Encoding: gzip" https://yourwebsite.com > compressed.html
Without compression: curl -H "Accept-Encoding: empty" https://yourwebsite.com > uncompressed.html
Compare file sizes using
The backend web server also need to support this, if its Nginx - check for gzip on if its Apache - mod_deflate,
OzzyI can not see any encoding header with
curl -I -H "Accept-Encoding: gzip, deflate,br" https://wiki-test.company.com
