Open application by A Href link

[ziycon]

I have the need to run an applicationon once a user clicks a link on a website. I've googled it and the link should be along the lines of:

<a href="appname://127.0.0.1:1234">join</a>

I can't get it to work for the life of me, are there standards or procedures for getting links like this to run applications?

As always any help much appreciated.

As far as I know the app has to register itself on the system as a protocol handler... you can probably find some way to do it through the likes of the windows registry, but being able to respond to these urls is a client-side thing.
For example, href="irc://" doesn't mean anything to my browser because I don't have any IRC client installed, but I think if I had mIRC installed, it'd launch and connect.
