i have a strange requirement. I want to access a page on my site through a link say www.abc.com/downloads/file.txt but i also want that if anybody enters only www.abc.com/downloads it should not be accessible or it should display access denied. How can i do that???????
Disable directory browsing on your webserver.
Why make it inaccesible? That would be a problem if you ever have a bad link.
You can better create a index.htm file in /downloads that redirects to some custom error page, or to another page (like /downloads/file.txt).
It would work the same with only one question mark, also.
