getting base url of web site's root (absolute/relative url)
- by uzay95
I want to completely understand how to use relative and absolute url address in static and dynamic files.
~ :
/ :
.. : in a relative URL indicates the parent directory
. : refers to the current directory
/ : always replaces the entire pathname of the base URL
// : always replaces everything from the hostname onwards
This example is easy when you are working without virtual directory. But i am working on virtual directory.
Relative URI Absolute URI
about.html http://WebReference.com/html/about.html
tutorial1/ http://WebReference.com/html/tutorial1/
tutorial1/2.html http://WebReference.com/html/tutorial1/2.html
/ http://WebReference.com/
//www.internet.com/ http://www.internet.com/
/experts/ http://WebReference.com/experts/
../ http://WebReference.com/
../experts/ http://WebReference.com/experts/
../../../ http://WebReference.com/
./ http://WebReference.com/html/
./about.html http://WebReference.com/html/about.html
I want to simulate a site below, like my project which is working on virtual directory.
These are my aspx and ascx folder
http://hostAddress:port/virtualDirectory/MainSite/ASPX/default.aspx
http://hostAddress:port/virtualDirectory/MainSite/ASCX/UserCtrl/login.ascx
http://hostAddress:port/virtualDirectory/AdminSite/ASPX/ASCX/default.aspx
These are my JS Files(which will be use both with the aspx and ascx files):
http://hostAddress:port/virtualDirectory/MainSite/JavascriptFolder/jsFile.js
http://hostAddress:port/virtualDirectory/AdminSite/JavascriptFolder/jsFile.js
this is my static web page address(I want to show some pictures and run inside some js functions):
http://hostAddress:port/virtualDirectory/HTMLFiles/page.html
this is my image folder
http://hostAddress:port/virtualDirectory/Images/PNG/arrow.png
http://hostAddress:port/virtualDirectory/Images/GIF/arrow.png
if i want to write and image file's link in my ASPX file i should write
aspxImgCtrl.ImageUrl = Server.MapPath("~")+"/Images/GIF/arrow.png";
But if i want to write the path hard coded or from javascript file, what kind of url address it should be?
