I have a php application that posts a shopping cart order to network merchants for credit card processing. &nbsp;I have selected to have the response posted to my php application that is running on a http site. &nbsp;Only a response code is coming back, but when I test it I get the warning message about moving from a secure to unsecure site. &nbsp;The credit card transaction has already happend, but do I still need a certificate or is there another way to handle this response from network merchants? <br />
Thanks.
