Server.MapPath specifies the relative or virtual path to map to a physical directory.

1. Server.MapPath(“.”) returns the current physical directory of the file (e.g. aspx) being executed

2. Server.MapPath(“..”) returns the parent directory

3. Server.MapPath(“~”) returns the physical path to the root of the application

4. Server.MapPath(“/”) returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)

An example:

Let’s say you pointed a web site application (http://www.example.com/) to

C:\Inetpub\wwwroot
and installed your shop application (sub web as virtual directory in IIS, marked as application) in

D:\WebApps\shop

For example, if you call Server.MapPath in following request:

http://www.example.com/shop/products/GetProduct.aspx?id=2342
then:

1. Server.MapPath(“.”) returns D:\WebApps\shop\products

2. Server.MapPath(“..”) returns D:\WebApps\shop

3. Server.MapPath(“~”) returns D:\WebApps\shop

4. Server.MapPath(“/”) returns C:\Inetpub\wwwroot

5. Server.MapPath(“/shop”) returns D:\WebApps\shop
