Example 1

For the example below, the file test.asp is located in C:InetpubWwwrootScript.

The file Test.asp (located in C:InetpubWwwrootScript) contains the following code:

<%
response.write(Server.MapPath("test.asp") & "<br />")
response.write(Server.MapPath("script/test.asp") & "<br />")
response.write(Server.MapPath("/script/test.asp") & "<br />")
response.write(Server.MapPath("script") & "<br />")
response.write(Server.MapPath("/") & "<br />")
response.write(Server.MapPath("") & "<br />")
%>

Output:

c:inetpubwwwrootscripttest.asp
c:inetpubwwwrootscriptscripttest.asp
c:inetpubwwwrootscripttest.asp
c:inetpubwwwrootscript
c:inetpubwwwroot
c:inetpubwwwroot
