On the "handler installation" part, instead of doing what the guide said, replace by the code I sent.<br></div>On this code you are registering more one handler at access phase (pushing more one position on the array "h = ngx_array_push")<br>
</div>and telling that this handler will be the function you have developed.<br><br></div><div>With that, nginx will execute any access handler configured by other modules including yours, and than execute the final handler.<br>
