Hi, all.

I need a help in the following question.  
I send a request to the nginx server and I need to support only 1.1  
version of the http protocol. If version is differ from “1.1”, the error  
code should be sent in the response.  
For this purpose I set “err\_status” parameter of the ngx\_http\_request\_t  
to error code and then call  
ngx\_http\_discard\_request\_body(ngx\_http\_request\_t \*r);  
After that I call ngx\_http\_send\_header(ngx\_http\_request\_t \*r) and  
ngx\_http\_output\_filter(ngx\_http\_request\_t \*r, ngx\_chain\_t \*chain);  
(where chain is NULL). But in this case client receives 0 bytes in the  
response.

Could you help me to find a problem?

NOTE: If version is set to “1.1” in the request, the response is  
successfully sent and has OK status
