How can I specify the relative path for a file

Suppose you have following file hierarchy:

default.aspx
Admin/login.aspx
Misc/testpage.aspx

And you are on the login.aspx and want your user to navigate to the default.aspx (or testpage.aspx) file. Then you can use

• Response.Redirect (‘../default.aspx’)
• Response.Redirect (‘../Misc/testpage.aspx’)
