Does the reCAPTCHA usercontrol post a request to http://www.google.com/recaptcha/api/verify to verify the entered text matches the captcha, or is this done in the dll?

What I'm asking is when you call Page.IsValid or repatcha.IsValid, does that make an API call to Google? – Jamie Carruthers Sep 21 '11 at 15:28

Turns out it does make requests to Google.
The first is a request from the client for a captcha image
The second is a request from the server to validate the entered text against the image
