In the ASP.NET programming, it is often necessary to obtain the information about the URL. There are a variety of methods in the request to obtain the URL information, but I often have forgotten the specific role of various methods. Today I wrote a test program and put various kinds. The results obtained by the method are listed, and they will be directly referred to when used. url address test is http://www.test.com/testweb/default.aspx, results were as follows: Request.ApplicationPath: / testweb Request.CurrentExecutionFilePath: /testweb/default.aspx Request.FilePath: /testweb/default.aspx Request.Path: /testweb/default.aspx Request.PathInfo: Request.PhysicalApplicationPath: E: / WWW / testweb / Request.PhysicalPath: E: /WWW/testweb/default.aspx Request.RawUrl: /testweb/default.aspx Request .Ur.ab/default.aspx request.ur.absolute.com/testweb/default.aspx request.url.host: www.test.com request.url.localPath: / TestWeb / Default.aspx
