Source: nginx Version: 1.6.2-5 Tags: patch jessie sid experimental Hi,
None of the currently available nginx packages (-light, -full, -extras)
have the HTTP Gunzip module[1] enabled. All that is needed for this
module to be included is a --with-http_gunzip_module switch.
Please consider enabling it. People have already reported the need for
it[2] and the official response is "use nginx' upstream repository".
For a comparison of the "official" nginx upstream repositories and the
Debian packages, see my user page[3].
Enabling support for gunzip enables the HTTP Substitution module to
replace data in a gzip-compressed page. Without this module, HTTP
compression has to be disabled or the substitution filter will fail.
This unfortunately leads to reduced throughput.
The official documentation[1] describes a use case, I have another one
where a nginx in a LAN has to rewrite some data. Without gunzip, I
forcefully have to disable HTTP compression. Simplified configuration:
proxy_http_version 1.1;
proxy_set_header Accept-Encoding "";
sub_filter '<title>' '<title>TEST: ';
proxy_pass http://$http_host$request_uri;
With gunzip enabled, this can be used instead:
proxy_http_version 1.1;
gunzip on;
gzip_disable ".";
sub_filter '<title>' '<title>TEST: ';
proxy_pass http://$http_host$request_uri;
(gzip_disable is needed because the author of gunzip had a different use
case in mind. Without this option, as an optimization nginx does not
decompress the proxied data for a client which breaks the substitution
filter.)
Since the Gzip module is already enabled for nginx-full and
nginx-extras, please consider enabling it for both of them. Otherwise,
please enable it just for nginx-extras if you think that the use cases
are rare. The attached patch is based on the collab-maint repo and
tested on Wheezy-backports (and on a half-upgraded Jessie image as well
:-)).
