Re: [go-nuts] Is there a way to capture the error by "http.MaxBytesReader"?

[Zhaoxun Yan]

Thanks a lot Olly!
I tried to do some research, here is my code, does it look OK?
```
r.Body = http.MaxBytesReader(w, r.Body, con.SizeLimit) 
defer r.Body.Close()

_, err := io.Copy(ioutil.Discard, r.Body)
if err != nil {
ip := r.Header.Get("X-Real-Ip")
               fmt.Println("someone just send an oversized request from", 
ip)
http.Error(w, "Request body exceeds the size limit", 405)
}else{
               fmt.Fprintf(w, "You just sent a legitimate request to the 
server!")
       }
```
