why do i get a 404 when adding a query string to a url

[eluser]sfurrh[/eluser]
The following url works:

http://localhost/login

But if I add a query string to it like:

http://localhost/login?curl=something

Then I get a 404.

What's up with that?

The = sign isn't 'valid' by default - CodeIgniter checks the url for characters which could cause problems, if there are, an error gets triggered. You can add "\=" to Allowed URL Characters section of config.php

why wouldn't it be valid (other than it is not among the allowed characters)? how else would you specify GET parameters?

Think its more of a security thing, as GET is disabled by default in CI. Just add "\=" (without the quotes) to the end of the string in config.php, and it should work.
