Maxim,

You are right. Since I need to make a hash of the original request's body, I do make call to ngx_http_read_client_request_body().

What's the best way to decrement the count then? Simply "r->count--;" before returning from the module.

By the way, in my access phase module, I need to send an subrequest and wait for its response asynchornously. ngx_http_read_client_request_body() also works asynchornously with a callback function, which apparently is not able to send a subrequest. What I did is registering two handlers in access phase. The first one does nothing but reading the request body only. The second one does the real work (subrequest, etc.). Does it sound right?

Thanks!!
