How to Specify “Vary: Accept-Encoding” header in .htaccess

Question

Google PageSpeed says I should \"Specify a Vary: Accept-Encoding header\" for JS and CSS. How do I do this in .htaccess?

Answer 1

I'm afraid Aularon didn't provide enough steps to complete the process. With a little trial and error, I was able to successfully enable Gzipping on my dedicated WHM server.

Below are the steps:

• Run EasyApache within WHM, select Deflate within the Exhaustive Options list, and rebuild the server.

• Once done, goto Services Configuration >> Apache Configuration >> Include Editor >> Post VirtualHost Include, select All Versions, and then paste the mod_headers.c and mod_headers.c code (listed above in Aularon's post) on top of on another within the input field.

• Once saved, I was seeing a 75.36% data savings on average! You can run a before and after test by using this HTTP Compression tool to see your own results: http://www.whatsmyip.org/http_compression/

Hope this works for you all!
