hxxp开头的网站是怎么个情况？？？

其实就是http.
hxxp://, sometimes h**p://, is used in URLs (web links) to obscure the fact that one is linking to a http:// web site. It is generally used to avoid automatic recognition by computer programs. For a user to follow this link, it is usually necessary to manually copy-paste the link onto the web browser's address bar and replace the 'x'es with 't's.
不知道你看不看的懂.一般病毒才这么用

不可能的...还没这个协议

除非 hxxp.xxx.com

可能是个二级域名

一般网站的是http，指的是传输协议是http（超文本传输协议）。还有比较常见的是ftp开头的，就是文件传输协议。至于hxxp我还是第一次听说，呵呵。
