I’m an avid Fluid user - with so much of my work and personal life moving into the browser, I like having site specific browsers set up for things like Basecamp and Google Docs. They feel more like real applications and I get to use Firefox for browsing.

My one problem is links from other apps, such as when someone sends me an email with a Basecamp link. Ideally, I’d want this to open not in my default browser but in the site specific browser I have already created for Basecamp.

Is there a way to do this on OS X? Direct all links that match a certain pattern to one application, all links that match another to a different application and anything else goes to my default browser.

Some cursory googling turns up nothing. I noodled on it for a sec and thought this would actually be a pretty cool app to have - call it LinkProxy or perhaps something less lame. You could set LinkProxy as the system default ‘browser’ and then it could do the pattern matching and redirecting for you. If there are enterprising Mac devs out there looking for something to do, call me and lets put our heads together. I’d put some real money behind this.

UPDATE Wow, thanks to everyone who recommended Choosy it’s precisely what I wanted. If you’ve ever used a single serving browser or multiple browsers (Safari for the real you, Camino for your alter ego) Choosy is excellent.
