request.getPathInfo()

[flashroom]

举例：
http://localhost:7001/myservlet/somepath/test?someparam=somevalue
request.getPathInfo()：返回/somepath/test
request.getRequestURL()：返回http://localhost:7001/myservlet/somepath/test
request.getRequestURI()：返回/myservlet/somepath/test
request.getServletPath()：返回/myservlet
request.getQueryString()：返回someparam=somevalue

[signboy]

javascript:
location.href

[aleccheung]

jsp:
request.getRequestURI();//从根目录起 /Expert/topic/1633/1633171.xml?temp=.7674372
request.getQueryString(); //后边参数 temp=.7674372
或
JavaScript
window.location;
的结果
http://expert.csdn.net/Expert/topic/1633/1633171.xml?temp=.7674372

http://localhost:7001/myservlet/somepath/test?someparam=somevalue
request.getPathInfo()：返回/somepath/test
request.getRequestURL()：返回http://localhost:7001/myservlet/somepath/test
request.getRequestURI()：返回/myservlet/somepath/test
request.getServletPath()：返回/myservlet
request.getQueryString()：返回someparam=somevalue

我只需返回http://localhost:7001/myservlet/somepath用何方法?
谢谢!
