Hello, I wrote to Igor but do not have the response so I write my question here and please help me. Firse of all, excuse me for my bad english!!! I hack the module “ngx\_http\_gzip\_static\_module.c” and I know that if client demande a file A, for example, the server NGINX will search the file “A.gz” and if it exist, Server will uncompress this gz file and the Server will serve the file uncompress of A.gz. It is not my objectif. My objectif is if a client demande a file B, for example. The server will search the file B.gz(compressed file) and serve this file if it exists. Client will receive file B.gz, not file B uncompressed. I lost for weeks for hacking this function but do not success. Please help me to figure out how I can realize this. Thanks for your help.

This is incorrect. The gzip\_static assumes there are two files with identical contents: foo foo.gz The “foo” file (uncompressed one) will be returned to clients which doesn’t support gzip. The “foo.gz” file (compressed one) will be returned to clients which support gzip. If you want nginx to uncompress a gz file, you have to use recently introduced gunzip module, see [Module ngx\_http\_gunzip\_module](http://nginx.org/r/gunzip), along with gzip\_static set to “always”. > It is not my objectif.

I’m not sure I understand correctly what you want, but it looks like what you are asking for is “gzip\_static always”, as available in nginx 1.3.6+. See [Module ngx\_http\_gzip\_static\_module](http://nginx.org/r/gzip_static) for details. – Maxim D. > **[F5 NGINX: Built for cloud-native apps.
