limiting access to files with asp.net

is there any way i can make a file only accessible to certain users of my
website? my files are to large to copy to a temp directory and they are of
many types, .exe .xsl .xml etc. i want an href to each file but only allow
users who have the right login-info in their session variable to get to the
files in their directory. is there something built into .net for doing this?
do i need to do some kind of isapi filter and then stream them?

You could map all those extensions to the ASP.NET DLL :

Another option would be to store those files outside of the dir and stream
them to the browser using a page (that can perform this check) :

file that is not under stored under the web site).

You can limit access to a folder by using settings in web.config. Look for
the <authorization> element in your web.config file and look it up in online
help (if using VS), or at msdn.microsoft.com/library

You will get better response to your questions by posting in the appropriate
newsgroup. In this case:
