#477 closed defect (invalid)

gunzip does not decompress gzip static content for clients that do not support gzip encoding

Reported by: Nick B Owned by:

Keywords: gzip_static, gunzip Cc:
uname -a: Linux 2.6.32-52-generic-pae #114-Ubuntu SMP Wed Sep 11 19:15:42 UTC 2013 i686 GNU/Linux
nginx -V: nginx version: nginx/1.5.7

Using the following directives in the http section of the conf file:

gzip_disable msie6;
gzip_vary on;
gzip_http_version 1.1;
gzip_static on;
gunzip on;

With a gzip file "index.html.gz" and no ordinary file "index.html" in the root directory

curl -H 'Accept-Encoding: gzip,deflate' - Works
curl - returns 404 File Not Found

Through a hack I can get it to return an uncompressed (using gunzip module) version if I comment out the second condition check from ngx_http_gzip_static_module.c:ngx_http_gzip_static_handler L112:

if (gzcf->enable == NGX_HTTP_GZIP_STATIC_OFF) {



if (gzcf->enable == NGX_HTTP_GZIP_STATIC_ON) {

rc = ngx_http_gzip_ok(r);

} else {

/* always */
rc = NGX_OK;


I'm not familiar with the nginx code base so this may not be the most appropriate place. It seems the function ngx_http_gzip_ok checks whether the client can accept gzip encoding. Perhaps this function should take into consideration whether the gunzip module is activated.

There is gzip_static always to do what you want.
