1. We use curl 7.51.0 on Windows/Mac/iOS/Android in our APP.

2.IP address
Our APP: 10.184.118.143
Http Proxy Server: 100.106.24.155

3.Our APP sends file via Http Proxy Server to file server.
Our APP --> Http Proxy Server --> file server

4.We found an issue:
The file server was shut down during sending file data, the curl can't stop sending data after it received FIN from Http Proxy Server until file data was sent finished.

5.We think that the code should be modified as bellow:
Curl_read function in curl-7.51.0\lib\sendf.c
