help with cassini webserver

hey,

im a newbie when it comes to asp.net and creating pages with visual studio.net 2003. Therefore, i'm learning it but to do that i need a virtual srver on my machine. I have win xp home so i can't have IIS and create a virtual directory thorugh that. i downloaded cassini webserver which doesn't need IIS installed. Now, the file that i want to create in VS.net wants to save it in
http://localhost/WebApplication1. and i want to use cassini so that the file will be saved in c:\WebApplication1. does anybody know what to type in the application directory option of cassini.

note: i have saved the cassini.dll assembly as a assembly cache in .net framework configuration. just need further help. thanx. plz give ur ideas
