What if you did this. Have a hidden form that would pass a value and one with the same value encrypted.
<input type="hidden" name="foo1" value="#now()#"> <input type="hidden" name="foo2" value="#Encrypt(now(), 'MyKey')#"> If the values don't match on the page it is submitted to, the form gets rejected. <cfif Encrypt(form.foo1, 'MyKey') IS NOT Encrypt(form.foo2, 'MyKey')> I hate spam. <cfelse> Its all good. </cfif> Thoughts?
