最近研究了一下代码，发现如果把send 和recv 得到的buffer 长度和字母打印出来，得到的长度是一样的，但实际buffer里的数据长度却不一样。实际收到的字节比发出的字节要多一些。很奇怪啊，为什么会这样？加密不是每个字节一一对应的吗？这样解密是才能得到正确的数据。但是又能正常工作。好奇怪的现象。

因为历史兼容性的原因，根据http1.0/1.1规范，代理必须从absolute uri中提取host，而不是从host head field中提取。

https://tools.ietf.org/html/rfc2616#section-5.1.2
The absoluteURI form is REQUIRED when the request is being made to a proxy.
...
Note that the proxy MAY forward the request on to another proxy or directly to the server specified by the absoluteURI.

section-5.2

1. If Request-URI is an absoluteURI, the host is part of the
Request-URI. Any Host header field value in the request MUST be
ignored.

最近GFW更新算法，mproxy是不是不能用了？？ 今天早上到公司，突然就不能用了，
下面 agent端的错误，server端没有日志输出。。。：

就要不支持win用户

路由器 ./mproxy -l 8000 -d 模式运行
手机端直接填入代理IP和端口，路由器可以收到信息，但是一直报错

不知道是哪里出问题了

Your browser sent a request that this server could not understand.
Request header field is missing ':' separator.
erral|utmcct=/download.html

请求链接:http://pyserial.sourceforge.net/

就是设置连接的时候需要账号和密码

启动之后会自动运行相同的进程多个

454行 buffer[i] ^= 1;
这一句有什么用呢？还望不吝赐教

请问是不是开一条连接就开一条进程了？windows下也是这样

when I use it to connect youtube it can't work , just show Read Http Header failed.

怎么用mproxy无法打开此网站：http://dafahao.com/?
我用其他的翻#墙程序能打开。

测试SwitchyOmega后,结论是不支持您的客户端.

其他网站可以正常用

我有个需求场景：
将http消息拆包到传输层，对端在传输层接收tcp/udp报文，这是否能通过mproxy实现？
