[Pkg-nginx-maintainers] Bug#844054: nginx-full: ngx_http_sub_module not working

[TC Meggs]

Package: nginx-full
Version: 1.6.2-5+deb8u4
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

   I attempted to use the sub_filter directive in a location block.

   proxy_pass http://127.0.0.1:3500/;
   proxy_set_header Accept-Encoding '';

   sub_filter 'abc' 'xyz';
   sub_filter_once off;
   sub_filter_types *;

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

   I attempted to make a request to the nginx server for the location block in question.

   * What was the outcome of this action?

   The response from the server was not substituted as expected. 

   * What outcome did you expect instead?

   I expected that the server would substitute the string.
   
I copied an identical configuration block to an Ubuntu server and it worked without issue, Ubuntu 16.04.1 LTS (Xenial Xerus) running nginx-full 1.10.0-0ubuntu0.16.04.4.
