通过socket
得到普通web 请求的内容如下：
ie输入tom.com
GET http://tom.com/ HTTP/1.1
Host: tom.com
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; ja; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5
Accept-Language: ja,en-us;q=0.7,en;q=0.3
Accept-Encoding: gzip,deflate
Accept-Charset: Shift_JIS,utf-8;q=0.7,*;q=0.7
Keep-Alive: 300
Proxy-Connection: keep-alive
Cookie: IPLOC=CN1102; TOM_Visit_Times=1; TUV=1161750563453287

msn连接的时候得到：
CONNECT login.live.com:443 HTTP/1.0
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727; IDCRL 4.000.248.1; IDCRL-cfg 4.0.5633.0; App MsnMsgr.Exe, 8.0.812.0, {7108E71A-9926-4FCB-BCC9-9A9D3F32E423})
Host: login.live.com
Content-Length: 0
Proxy-Connection: Keep-Alive
Pragma: no-cache

我在login.live.com前加上 “http://”或者"https://"都不行。
那位有这方面经验？
