Expected Behavior

http代理应和git正常配合工作

Current Behavior

启动的http代理能够正常进行网页访问等操作，但是无法作为git的http代理。具体步骤见后文

Possible Solution

水平不足以提出

Steps to Reproduce

具体操作如下：

软件版本 free_13.1 (Windows平台)
使用如下命令启动http代理 proxy http -t tcp -p localhost:8899
在~/.ssh/config内进行如如下配置

Host gitlab.domain.com
  ProxyCommand "C:\Program Files\Git\mingw64\bin\connect.exe" -H localhost:8899 %h %p

测试ssh连接情况：OK

ssh -T git@gitlab.domain.com
Welcome to GitLab, @user!

测试clone/fetch等git相关操作：出现问题

git clone git@gitlab.domain.com:user/gitdemo.git
Cloning into 'gitdemo'...
ERROR: Unexpected http response: ''.
FATAL: failed to begin relaying via HTTP.
kex_exchange_identification: Connection closed by remote host
Connection closed by UNKNOWN port 65535
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
