How to know if gzip is being used?

Question

PHP

I put the site on the open server and write it in htaccess:
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application /x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
How do I know if it even worked? The network shows 85kb on the local and on the hosting. checkgzipcompression.com writes that up to 15kb is compressed and 85 is unzipped.

Answer 2

Check the headers of the file being sent, in theory it should be written in them if the file is compressed.
