Firefox 28.0 developer tools error with Accept-Encoding
Hi,
When i do an SPDY request to a SPDY capable web server (NGINX) Firefox developer tools says that the Accept-Encoding request header is added.
Accept text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding gzip, deflate Accept-Language nl,en-US;q=0.7,en;q=0.3 Cache-Control no-cache Connection keep-alive Cookie originURI= Host $host Pragma no-cache User-Agent Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0
When i enable debugging in NGINX there is no Accept-Encoding request header.

- Is there a reason not to sent the accept-encoding header when doing a SPDY request? (Chrome is sending this request header with SPDY).
Regards,
Frank

This is because it already does by default. http://kb.mozillazine.org/Network.http.accept-encoding
Check out the about:config page and look what it is set to.
Hope this helps.
But the problem is that the request header accept-encoding is not sent when doing a SPDY request while Firefox says it does.
Oh I see, the SDY request version of the request does not have encoding but the Web dev tools version of the request does have it.
SDY is an open Google project that uses this type of compression: https://developers.google.com/speed/w.../compression is also removes some headers https://developers.google.com/speed/a.../spdy-for-mobile
Then there is this: https://developers.google.com/speed/a.../gzip It looks like the server/spdy is ignoring that encoding header?
Which one does it request first? I assume that the request is from Firefox, then is received by the spdy proxy, where it looks like it is ignored?

Maybe this makes my request more clear: http://trac.nginx.org/nginx/ticket/542
It seems that Firefox won't send Accept-Encoding header over SPDY and that caused confusion and when i tried to debug developer tools told me that Accept-Encoding is sent.
