Protocol handler with multiple arguments

Question

I created an application to act as a protocol handler, the registry are set up according to http://msdn.microsoft.com/en-us/library/ie/aa767914(v=vs.85).aspx

Then in the webpage I have something like:

<a href="testapp:arg1">Test App</a>

If I click the link, the app is launched and "testapp:arg1" is passed in as an argument.

Now I want to pass multiple arguments to the handler. I'm guessing in the "command" registry key, I would have "path_to_exe" "%1" "%2". However I can't figure out how to write the html link to supply multiple arguments.

Is it possible to pass multiple arguments? If so, how do I do it and are there differences between different browsers?

In Registering an Application to a URI Scheme, it says that

When a user clicks a link containing your custom URI scheme, Windows Internet Explorer launches the pluggable protocol handler registered for that URI scheme. If the specified open command specified in the registry contains a %1 parameter, Internet Explorer passes the URI to the registered pluggable protocol handler application.

which means, spaces will be handled as the character in the whole URI.
