Passing varible types though mod-rewrite

howdy, I'm using the get method on my current project. my links refer to <a href='?p=". $path … and i'm getting there values with if(isset($_GET['p'])) …

everytime i click a link the url in the adressbar changes to mydomain.com/?p=files/path/subpath

i wonder if i can somehow use mod_rewrite or anything else i order to get a prettier url. i'd love to get rid of the "开发者_如何学C/?p=files/" part in my url. it would be cool if the endresult would look like this:

mydomain.com/path/subpath

is that even possible? regards matt

If you're using that type of URL, you are probably doing something wrong in your program.

For example, let's say you use an htpasswd file to store your web site users. And I pass in ?p=../.htpasswd. Now I can break in as the user who has 'please' as their password. Or I pass in ?p=/etc/passwd, and get a list of the valid users on your system.

Yes, you can get rid of the ?p= by using mod_rewrite ( http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html ). But you should really make sure you know what you're doing and that arbitrary path specifications aren't possible.
