Facebook like button is liking wrong url

Question

First off, I saw similar posts already, but they weren't exactly what I am asking.

I used the Facebook Dev to create a like button for my website, stuck the code in and the the button showed up. The only issue is that it likes the wrong url when I click the button.

I'm pretty sure the issue is that I have it set to redirect automatically from mydomain.com to the most recent post. I think this is gumming up the works with the like button and causing it to like mydomain.com/mostrecentpost instead of simply liking mydomain.com.

Is there a way to correct this issue without having to get rid of the redirect (because that isn't an option)?

Sorry if that was a little wordy, wanted to make sure I explained the issue fully.

Either don't redirect in those cases where the user agent header of the request points to it being Facebook's scraper ;

or set the canonical URL of http://example.com/mostrecentpost to just http://example.com/ using the appropriate Open Graph meta tag. (Although that would mean you would not be able to like a single post any more, because all of your posts would just point to your base domain as the “real” website; so the first is probably the better option.)
