ASP.NET中Request.ApplicationPath、Request.FilePath、Request.Path、.Request.MapPath
转载自：https://www.cnblogs.com/caishuhua226/p/4178692.html
1.Request.ApplicationPath->当前应用的目录
2.Request.FilePath->对应于iis的虚拟目录
如 URL http://mockte.com/1/index.html/pathinfo
FilePath = /1/index.html
3.Request.Path->当前请求的虚拟路径
Path 是 FilePath 和 PathInfo 尾部的串联。例如 URL http://mockte.com/1/index.html/pathinfo
那么Path = /1/index.html/pathinfo
4.Request.MapPath(string url)->将url映射为iis上的虚拟目录
这个目录都是相对于application的根目录的
于Server.MapPath相比,不会包含类似c:/这样的路径
可以理解为是相对路径(对比的Server.MapPath就是绝对路径)
5.Server.MapPath(string url)->将url映射为服务器上的物理路径
例如 http://mockte.com/1/index.html 假设你的应用程序在c:/iis/MySite中
那么就是 c:/iis/MySite/1/index.html
6.底下这张表就是根据Browser Request 的网址相关的属性的用法
