If the user clicks on a https: URL and the browser does not
support SSL, it doesn't contact your server in any way so
you have no way to know it failed.

You might possibly get around this with trying to load a subframe from
a secure page with JavaScript, which is Turned Off (tm). Javascript
is more likely to be turned off than SSL.

You should provide the form via SSL (so the lock icon shows on the
page while the user is filling in the information). This also tests
that SSL works before the user spends time filling in the form and
then has it not work. You can provide a second link on the page
that leads TO the form, for use in case the first one doesn't work.
