title: nginx modifying the content in compressed response
body: <p>In our project we have a problem where we have to edit the response content that is served through ngnix. For the uncompressed responses we are able to do it through <strong>sub_filter</strong>  module of ngnix, but for the compressed response we have to uncompress the response and edit teh response for that we are using the <strong>gunzip</strong> module. </p>
  
  <p>The problem is when we use the gunzip the response content that is render through ** curl** command contains the changes that we made , but when the same thing is rendered through browser the response does not contain our changes. Can any one explain me what might be the issue.</p>
