Setting Web Server Permissions
It is important to understand the distinction between Web server
permissions and NTFS permissions. Unlike NTFS, Web server permissions
apply to all users accessing your Web and FTP sites. NTFS permissions
apply only to a specific user or group of users with a valid Windows
account. NTFS controls access to physical directories on your server,
whereas Web and FTP permissions control access to virtual directories
on your Web or FTP site. For more information, see Web and FTP Sites.

By default, Web and FTP access permissions use the Windows account
IUSR_computername. When users access your site, using anonymous
authentication, they use this account. By default, IUSR_computername
is given NTFS permissions by IIS for the actual folders that comprise
the Web or FTP site. You can, however, change these permissions for
any folder or file in your site. For example, you can use Web server
permissions to control whether users visiting your Web site are
allowed to view a particular page, upload information, or run scripts
on the site. For more information, see About Access Control.

Important

If Web permissions and NTFS permissions differ for a directory or
file, the more restrictive settings are used.
////////////////////////////////////////////////////

The last statement says that if Web permissions and NTFS permissions
differ for a directory or file, the more restrictive settings are
used.
But then in my case the web permission in IIS for
http://localhost/WebApplication2(actual physical directory at
C:\Inetpub\wwwroot\WebApplication2) is set to read only but I am able
to write a file in the same directory........(default asp.net user
granted write NTFS permission in this directory)
Why???
