Asp. NET in Request.applicationpath, Request.filepath, Request.path,. Request.mappath

1.Request.applicationpath---Current application directory

2. Virtual directory corresponding to IISRequest.filepath
such as URL Http://mockte.com/1/index.html/pathinfo
FilePath =/1/index.html

3. Virtual path to the current request,Request.path
Path is the concatenation of the FilePath and PathInfo tails. For example URL Http://mockte.com/1/index.html/pathinfo
Then Path =/1/index.html/pathinfo

4.request.mappath (string url), map URLs to virtual directories on IIS
This directory is relative to the root directory of the application.
Does not contain a path like c:/, compared to Server.MapPath
Can be understood as a relative path (the Server.MapPath of the contrast is the absolute path)

5.server.mappath (string url), map the URL to a physical path on the server
For example http://mockte.com/1/index.html assume that your application is in C:/iis/mysite
So that's c:/iis/mysite/1/index.html.
