[PATCH] disable chunked filter don't change keepalive

[Wandenberg Peixoto]

Hi,

I don't know if there is some reason to disable keepalive if chunked filter
is disabled.
If don't have a reason for that I would ask to apply this patch to nginx
core.

                 ngx_http_set_ctx(r, ctx, ngx_http_chunked_filter_module);

-            } else {
-                r->keepalive = 0;
             }
         }
     }

I developed a module which delivery the same message to many users in a
chunked connection, because of that I disable chunked filter and make the
chunks myself to deliver to all users saving some memory and processing.

Everything is working fine, but without this patch I can not use keepalive
on my connections, because nginx chunked filter disable this feature when
it is disabled.

I hope you can accept this simple patch, regardless of my use case.

Regards,
Wandenberg
