Why is it, when I registered for eat2go, my browser told me I was in a secure zone, and when I am placing an order, it tells me I am in a mixed zone?

To make the order process as fast and simple as possible, the eat2go implementation of the Food-Port ordering portal is frame based. To eliminate the annoying and continuous refreshing of the display, as many web-based ordering systems do, in Food-Port, there are multiple active documents that communicate with each other during an ordering session. The registration form is a single document, and that is the difference. During the ordering process, eat2go employs several digital certificates, for different purposes. To prevent eavesdropping, these certificates are a part of a 128 bit based algorithm used to establish an encrypted connection with your browser. By design; however, some elements are not subject to this type of transport, like frame-set data, browser directives, graphic images and other non-sensitive materials. Hence, your browser may warn you that you are in a mixed security zone. In general; however, do not send sensitive or financial information on the Internet, unless you are sure that the HTTPS protocol is being used. In Microsoft Explorer®, for example, you can observe the details of the transmission and the protocol being used on the bottom activity bar. The initial URL display or any other indicator is not a definitive sign that HTTPS, instead of HTTP (Hyper Text Transport Protocol), is being used.
