Are there any unzip modules in nginx?

Question

I am writing a nginx filtering module as a proxy, I want 2 changes a bit of specific content

First, I need to unzip the gzip page .

Before I write my own ugly one, I want to know if there is already a module that can do this, because I think these are basic needs.

#include
