I have 2 pages to my web site, first page captures name, address, city, state, zip, phone, email. Second page captures credit card number, expiration date. I want code so that if someone leaves my site and does not return in under 5 minutes it will do a POST with all page 1 information to a URL. Obviously it will only pass information if page 1 is filled out.
That's basically it. Also needs to be cross platform, ASP, [url removed, login to view], C#, PHP, etc..
