Hi, goproxy is very good ,I love this soft. I test it in many case, and find that many time it return 500 error, some time it works well ,but some time make me can't use . Client send request to goproxy_server , use wireshark capture the packet ,it seem that ,goproxy_server do not send request to the real server and direct return 500. the server is www.artilib.cn.

How Can I deug the process and find out the real problem? my go compiler is 1.7.3

Hi,

Thanks for the kind words.

Can you try running the proxy with Verbose = true?
