服务器评测
某些网站通过http header信息限制下载文件，在linux下面可以使用wget来模拟realplay等的，http header信息。
wget –head “ClientID: WinNT_5.0_6.0.12.1056_play32_R30CND_zh-CN_686_axembed” –head “User-Agent: RMA/1.0 (compatible; RealMedia)” http://localhost/head.php
说明：每一个header信息项用一个 –head参数来指定，可以多次使用 –head参数。
下面是我的http://localhost/head.php获得的header的信息：
Array
(
[User-Agent] => RMA/1.0 (compatible; RealMedia)
[Accept] => */*
[Host] => localhost
[Connection] => Keep-Alive
[ClientID] => WinNT_5.0_6.0.12.1056_play32_R30CND_zh-CN_686_axembed
)
以下是下载成功和不成功的http链接信息记录：
