How to read form response URL variables in template? I have a basic login form that's talking to a separate server that's out of my immediate control. I'm trying to read the responses it's sending in the URL within the Craft template.
For example...

http://www.adacore.com/login?login=incorrect


I've only ever done it before in PHP. Is it possible with Craft/Twig to access these variables directly? Or should I just read the craft.request.queryString?

And change the template accordingly as needed.
I'd go with the built in craft functions.

craft.request.getQuery('login')
