I've set up my web forms and everything is good to go - except this whole HTTPS business.  I have a simple website, with one page to collect "Contact Us" info from potential clients.  I'm using Squarespace to create this website.

Question is, is there a way to get a return/error value from the web form?  In other words, if a user mistakenly uses http instead of https, they can still submit the form and it looks exactly the same (goes to the landing page which says "thanks").  The only difference is it doesn't go into the DB, no way to tell otherwise.

Anyone know a way around this?  Either how to force HTTPS (which I'm having a hard time with), or at least an error return value showing me that the web form did not work?

Any help is appreciated.
