Encode only part of url

Is it possible to encode every character of a url after the main domain name so our directory structure is less apparent? For example I’d like:

[url]http://www.mysite.com/admin/pagename.html[/url]

to become:

[url]http://www.mysite.com/%61%64%6D%69%6E%2F%70%61%67%65%6E%61%6D%65%2E%68%74%6D%6C[/url]

When I try this, IE says it can’t find the page even though the link in the status bar looks absolutely correct when I hover over the encoded link.

Thanks,
David
