eCommerce site requirements?

To ensure your users information is protected when communicating with them you will want to use SSL encryption on your server. The first step to doing this is to purchase an SSL Certificate which http://DynDNS.com offers. For instructions on creating an SSL certificate you can read through our How To article on the subject. https://www.dyndns.com/services/sslcert/howto.html

You will also need to install and configure your server with SSL as well. Apache has documentation on setting up the SSL Module here. http://httpd.apache.org/docs/2.2/ssl/

DynDNS also has their own instructions you can read through for another perspective. https://www.dyndns.com/services/sslcert/install.html

At an absolute minimum you need both an SSL certificate and to configure Apache to require SSL for the relevant pages. General information about SSL in Apache is here. At a minimum the following will be required in your httpd.conf (the exact location of this will vary according to your distribution, but it's probably under either /etc/httpd or /etc/apache or something very similar):

<Location /my/cart/path>

SSLRequireSSL

</Location>

Assuming your site is http://www.example.com then this will force access to anything starting with http://www.example.com/my/cart/path to be done over SSL. Note that there may be legal requirements on if or how you store the data you receive (such as credit card numbers). Make sure you understand both the legal situation where you live and in the USA since this is where the server is hosted.
