How does ASP. NET obtain the URL address in the address bar?

How does ASP. NET obtain the URL address in the address bar? See the following implementation method:

First:

Http://www.liehuo.net/liehuonet/default.aspx

Request. applicationpath:/liehuonet
Request. currentexecutionfilepath:/liehuonet/default. aspx
Request. filepath:/liehuonet/default. aspx
Request. Path:/liehuonet/default. aspx
Request. rawurl:/liehuonet/default. aspx
Request. url. absolutepath:/liehuonet/default. aspx
Request. url. absoluteuri: http://www.liehuo.net/liehuonet/default.aspx
Request. url. HOST: www.liehuo.net
Request. url. localpath:/liehuonet/default. aspx

Second:

Rawurl
The original URL of the current request.
Remarks

The original URL is defined
The part after the domain information in the URL. In the URL string
Http://www.liehuo.net/cn/introduct/lanmu_24_57.html, original URL
It is/CN/introduct/lanmu_24_57.html. The original URL contains the query string (if any ).

The URL for the test is http://www.liehuo.net/liehuonet/default.aspx? Id = 1. The result is as follows:

Request. applicationpath:/liehuonet

Request. currentexecutionfilepath:/liehuonet/default. aspx

Request. filepath:/liehuonet/default. aspx

Request. Path:/liehuonet/default. aspx

Request. pathinfo:

Request. physicalapplicationpath: e: \ www \ liehuonet \

Request. physicalpath: e: \ www \ liehuonet \ default. aspx

Request. rawurl:/liehuonet/default. aspx? Id = 1

Request. url. absolutepath:/liehuonet/default. aspx

Request. url. absoluteuri: http://www.liehuo.net/liehuonet/default.aspx? Id = 1

Request. url. HOST: www.liehuo.net

Request. url. localpath:/liehuonet/default. aspx

Get URL:
1. obtained through ASP. NET
If the URL for the test is a http://www.test.com/testweb/default.aspx, the results are as follows:

Request. applicationpath:/testweb
Request. currentexecutionfilepath:/testweb/default. aspx
Request. filepath:/testweb/default. aspx
Request. Path:/testweb/default. aspx
Request. physicalapplicationpath: e: \ www \ testweb \
Request. physicalpath: e: \ www \ testweb \ default. aspx
Request. rawurl:/testweb/default. aspx
Request. url. absolutepath:/testweb/default. aspx
Request. url. absoluteurl: http://www.test.com/testweb/default.aspx
Request. url. HOST: www.test.com
Request. url. localpath:/testweb/default. aspx

2. Get it through JS
