Don’t be lazy when configuring security certificates
Monday, 17 November 2008
If you’re going to offer a secure protocol to your users, don’t do what CSA Australia did, as I indicated in an earlier post.
Don’t configure your SSL certificate for your “www” subdomain and then just assume that your users will get to your website by typing in the “www” and that the webserver will automatically take care of the rest.
It won’t.
If your webserver is configured to automatically redirect to your “www” subdomain when the user hasn’t used specified the silly “dubya-dubya-dubya” prefix from your website address, then you must also change all your links to secure forms to explicitly use “https://www.”, instead of “https://” as the prefix for those links.
