Server Variable for page url

string url = HttpContext.Current.Request.Url.AbsoluteUri;
// http://localhost:1302/TESTERS/Default6.aspx

string path = HttpContext.Current.Request.Url.AbsolutePath;
// /TESTERS/Default6.aspx

string host = HttpContext.Current.Request.Url.Host;
// localhost

Path.GetFileName( Request.Url.AbsolutePath )

pramod.aspx

EXAMPLE (Sample URL)

http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QuerrString2=2

HttpContext.Current.Request.Url.Host
HttpContext.Current.Request.Url.Authority
HttpContext.Current.Request.Url.AbsolutePath
HttpContext.Current.Request.ApplicationPath
HttpContext.Current.Request.Url.AbsoluteUri
HttpContext.Current.Request.Url.PathAndQuery

localhost
localhost:60527
/WebSite1test/Default2.aspx
/WebSite1test
http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QuerrString2=2
/WebSite1test/Default2.aspx?QueryString1=1&QuerrString2=2


EXAMPLE (Sample URL)

http://localhost:60527/WebSite1test/Default2.aspx?QueryString1=1&QuerrString2=2
string url = Request.Url.Host;
localhost:2806 

"http://localhost:1234/Default.aspx?un=asdf&somethingelse=fdsa"

or like this:
"https://www.something.com/index.html?a=123&b=4567"

and you only want the part that a user would type in then this will work:
String strPathAndQuery = HttpContext.Current.Request.Url.PathAndQuery;
String strUrl = HttpContext.Current.Request.Url.AbsoluteUri.Replace(strPathAndQuery, "/");

which would result in these:
"http://localhost:1234/"
"https://www.something.com/"
