In a secure area of my site I have a form that asks for the credit card information. When a users clicks the continue button. I sometimes, not always, get a "Page Cannot Be Found" Error. The page is there, because you can refresh and continue, but some data is missing. This seems to be when someone enters the site for the first time, when there is no "history" or cached files.
Everything works without a glitch in a non-secure environment.
Any ideas? Has anyone run into or heard of any similar problems?
Thanks!
