Hi Maxim,

I am sending the response in the request handler which I registered for

in the NGX_HTTP_SERVER_REWRITE_PHASE handler. In my handler, I have the

following code to avoid responding multiple times as well. Still, I am getting

the error.

if (r->main->count > 1)
return NGX_DECLINED;


Bhasker.

The error indicate that you are trying to sent a response header
at the point where it was already sent. You have to invistigate
why and where it happens, and fix things. Most likely you are
trying to add your code in a wrong place.
