O.K., I see. Thank for clarifying. In those cases, a favicon will most
likely be already known.
But, take Opera's webmailproviders.ini for example. You have to manually
specify the icon location. It's not discovered automatically through other
means. If the user allowed registerProtocolHandler to add a webmail entry
to the file, being able to say what icon to load would be great. But, even
if a favicon (or other type of pic) can be discovered automatically, will
the browser pick the right one? Maybe there's a specific file that should
Now, if every UA's protocol configuration is going to be plain jane
text-only, then an icon for example isn't an issue.
