Long query string

[eluser]Unknown[/eluser]
First of all, hello to all of you. As you can see I am new to the forum, but I have been using CodeIgniter for some time now.

I have a project where I should change the site from php with no framework to CodeIgniter. I have done some thinking and I can't seem to find a nice way to handle long query strings.

Is there some nice and clean way to handle long query string?

Example:
http://www.site.com/page.php?param1=1&pa...ram4=dasda etc

And I would like to change it to something like
http://www.site.com/controler/...

Do you suggest some approach I should use here?

Thanks
