测试
实行以下命令：
javaserver.CustomAccept
在IE的地点栏中输出以下Url：
http://localhost:1234
CustomAccept在把持台中的运转了局：
GET / HTTP/1.1
Accept: */*
Accept-Language: zh-cn
UA-CPU: x86
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; InfoPath.1; InfoPath.2)
Host: localhost:1234
Connection: Keep-Alive
下面的运转了局就是IE向服务端收回的HTTP哀求头的内容。这个运转了局会依据客户机设置的分歧而有所差别。
