Prevention to access the root directory.

Hi,

I have my asp.net application  running well, but I have to prevent the listing of root directories.

 

Like my url is : www.abcd.com and in that I have folder of account, in which i have the accountPatient.aspx,

so the full url will be :  www.abcd.com/account/accountPatient.aspx

 

When I edit the accountPatient.aspx, it remains a www.abcd.com/account and when I press the enter key it is showing all the directories under account folder, so I need to prevent the showing of root directories and has to be redirect to Home page. Can any one knows how to do it? I searched upon the Google but I didn`t find a particular answer.

 

Thanks.
