We have two websites featuring two aspects of our business: metrology and robotics. As these two are related, we have many links between these two sites, and they are designed to work seamlessly - they even look similar.
We don't have any LOG IN forms on either one of the sites, but, we have "quote request" forms for different items. Many times, a customer will fill out their info in one of the forms and request the quote, I would save their contact info in PHP session variables and when they move onto another quote request during the same visit, their contact info is pre-filled in the form. It is convenient to the customer, but...
but, of course, once they leave one site and go to our other site, the session variables are lost.
Is there any way to retain the session variables values between two sites?
