Can I use the normal URL variables structure with CodeIgniter?

[eluser]KeyStroke[/eluser]
I've been using CodeIgniter for a while, and I noticed that the way it passes the variables in the URL is not flexible at all, and requires extra coding at many parts of the program.

So, is there a way to have some sort of hybrid? something where I can pass variables like this:

Code:

http://example.com/index.php/controller/function/?var1=5&var2=10

If not, then can I just use the original method? if so, then how does it work within CodeIgniter?
