I use gzip module of nginx to compress documents. When gzip is enabled nginx will automatically send content-ending of gzip with HTTP headers, right?
Without adding any PHP header
header() or HTML meta
http-equiv, this works perfectly. However, I have seen on online tutorial for adding header for gzip whether by PHP or HTML meta to assist browser to process gzipped data.
Is it really needed? Since I was not sure if this is needed on some conduction (that I am not testing), I asked this question for further clarification of the issue.
