Will my favorite Internet app take advantage of the new URL scheme?
Well-behaved Macintosh applications handle URL-related actions through InternetConfig. These applications will transparently use the new URL scheme, provided that you tell InternetConfig that the helper for the fab scheme is QuickestMirror itself. To do this,
1) select Edit Internet Config Preferences from the File menu in QuickestMirror; this should open the IC application
2) open the Helpers window
3) add QuickestMirror as a helper application for the fab scheme
4) Save the changes
There are notable exceptions, of course, such as Netscape, that will need an AppleScript kludge like this:
tell application "Netscape Navigator™"
register protocol "QMir" for protocol "fab"
end tell
This instructs Netscape to let QuickestMirror handle fab URLs. Please note that Microsoft Internet Explorer properly supports InternetConfig.
Eudora sports a peculiar, non-standard, and confusing way of dealing with InternetConfig. Hence, you won’t be surprised to learn that fab URLs do not auto-highlight. This is current as of Eudora Light 3.1.1.
