Why isn't my LinkedIn API authorization method working?

Question

I'm following the authorization instructions but I can't figure out how it's supposed to work. I'm sending a request to https://www.linkedin.com/uas/oauth2/authorization, and passing the required fields. The call succeeds and returns some authorization html, which I display, and it looks like this:

But the form containing the Allow Access button has an action of /uas/oauth2/authorizedialog/submit, and so clicking it fails, because there's no domain specified. Clearly it's supposed to be displaying some sort of authorization on the LinkedIn site, not my own. What am I doing wrong?

Answer 1

Argh, what I was doing wrong was trying to download the contents of the authorization url page, instead of simply redirecting to it. Redirecting to it does open the page on their site, and I can authorize, and then be redirected back to my own callback.
