Yes.  It has to look up the program that is registered to handle the
HTTP protocol.

It is not a single key, but several keys working together.  The Shell
recognizes that the specified filename begins with a URL protocol, so
it first opens the following key:

    HKEY_CLASSES_ROOT\<protocol> (in this case, <protocol> is "http")

It checks if the key has a "URL Protocol" value present.  If present,
it then checks if the following key exists:

    HKEY_CLASSES_ROOT\<protocol>\shell\<verb> (in this case, <verb> is
"open")

If it does, then the Shell executes the program specified in the
"command" subkey, or connects to the server specified in the "ddeexec'
subkey.

Refer to the following article for more details:

    Registering an Application to a URL Protocol
