How about:

UrlConnection connection = url.openConnection();
connection.getLastModified();
Not sure it this really works in all cases, but appears to be quite
suitable and easily extensible.
Yes, this works for many cases, but not for cases like where you have
an expiry date etc. What do you mean by "easily extensible"?
url.openConnection() actually returns a subclass of URLConnection
depending on the protocol of the URL.
So own protocol implementations can return own subclasses that implement
this (and other methods) accordingly.
And - at least theoretically - provide additional methods for handling
specific stuff, e.g. expiration dates.
