}

这是我的请求包答应出来如下：
GET / HTTP1.1
Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/xaml+xml, application/x-ms-xbap,application/x-ms-application, application/vnd.ms-xpsdocument, */*
Accept-Language: zh-cn
User-Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; InfoPath.2; .NET4.0C; .NET4.0E; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Host:www.baidu.com
Connection:Keep-Alive

结果socket没有返回
把URL改成www.163.com 结果socket返回:
HTTP/1.0 502 Bad Gateway
Cache-Control: no-cache
Connection: close
Content-Type: text/html

502 Bad Gateway
The server returned an invalid or incomplete response.


以上端口设置都是80  是不是请求包设置错误了 至少代理User-Agent:选项应该是linux的 但我认为这个没有影响？求指点

GET / HTTP/1.1
