Is it possible to attach URLHandler for plugin

Question

Hi, Guys.
I notice Facebook plugin can accept external URL protocol via web browser.
( URL : lightroom://com.adobe.lightroom.export.facebook/%23access_token=147.... )
Is it possible to attach Custrom URLHandler for my plugin ?
I can't find any information about it.
If someone know about this, please let me know.
Have a nice day.

The "lightroom://..." URL works fine in IE if I type it on the address bar, but it doesn't work (i.e. "Internet Explorer cannot display the webpage" error) if it comes in from the internet via an HTTP 302 redirect response.  Per Matt's suggestion, I added the originating site to my "trusted sites" (and even threw in my "lightroom://..." URL for good mesasure), but still no joy.  I guess Rob is having success driving his plug-in from IE, because his stuff is all local (right, Rob?).
So, I'm still curious if anyone has had success using IE to respond to the "lightroom://..." protocol (or any custom protocol, for that matter) when the request originated from the internet.  Anyone?

(p.s., if anyone's curious, here's a page describing how custom protocols are registered on Windows systems: http://msdn.microsoft.com/en-us/library/aa767914%28v=vs.85%29.aspx .  )
Update: Using IE, I discovered that if a user clicks on a link in a remote web page that has a "lightroom://..." URL, or the remote web page contains a
<META HTTP-EQUIV="refresh" CONTENT="0;URL=lightroom://... />
tag, it works.  IE (8 -- haven't tested others) is only choking on the HTTP 302 redirect.  :-(
