Have a look at Apple's Launch Services Programming Guide. You have to add CFBundleURLTypes to your apps Info.plist and register your app with LSRegisterURL().

Excerpt from Firefox.app/Contents/Info.plist:

    <key>CFBundleURLTypes</key>
    <array>
            <dict>
                    <key>CFBundleURLIconFile</key>
                    <string>document.icns</string>
                    <key>CFBundleURLName</key>
                    <string>http URL</string>
                    <key>CFBundleURLSchemes</key>
                    <array>
                            <string>http</string>
                    </array>
            </dict>
 ....
