Get URL of Previous page and current page in ASP.NET

In order to get the url of current page C# code is :

string currUrl = Request.Url.AbsoluteUri;

It will display the full URL as:
http://localhost:61653/WebSite1/Default1.aspx

In order to get the absolute path of the url  C# code is :

 string currPage = Request.Url.AbsolutePath;

Output is as :
/WebSite1/Default.aspx

There might come a case by which we want to know url of the previous page from where
it is navigated.

In order to get the url of previous page C# code is :

string prevUrl = Request.UrlReferrer.AbsoluteUri;

This will display the full url of previous page.

And if we just want to know absolute path only the code is :

string prevPage = Request.UrlReferrer.AbsolutePath;
