File Protect

Hi All,

I my project i have 10 files, people can go iview files # 1 to 8 as
free.
But on file # 9 I just want some certain group of people to get in and
same as file # 10 i just want some other group of people to get it. How

do I aproach this issue?


I want to use the Window authenticate this.


It is a webpage project, people can view it by type in the example
below:
(just an example)

Example: if
http://www.myproject.hrer/file1.aspx (everyone can view it)
and same for file2.aspx to file8.aspx.


but it people try to do this
http://www.myproject.hrer/file9.aspx then only some group of people can

view it, otherview error, no access


same for
http://www.myproject.hrer/file10.aspx file.


Thanks
