Content-Encoding not displayed in Response header when Accept-Encoding is either gzip or deflate

Question

I am using Firefox and when I set the Accept-Encoding to "deflate,gzip" I get "Content-Encoding: gzip" in the response header. When I use Accempt-Encoding as either deflate or gzip the "Content-Encoding" is removed from the header.

Can anyone please explain me why ? Is there any apache configuration I need to consider ?

Answer 1

Refer to the RFC it offers details about which values can be used in Accept-Encoding and how a server tests whether a content-coding is acceptable, according to an Accept-Encoding field, using these rules,
