passing a url in the url

[eluser]deadelvis[/eluser]
Hi
I'm trying to write a generic redirect function on my main controller. What is the best way to pass a url in the url?

Generating links with format (url encoded url)...

Code:

<a href"http://mysite.com/redirect/http(%)3A(%)2F(%)2Fothersite.com(%)2Fsomepage.php">

... leads to "Page not found" error, due to the (%)2F in the string being interpreted as /.

Any ideas on how to do this easily?

PS: Percentage sign % substituted by (%) for display reasons
