Force the Use of HTTPS (SSL)


As it turns out, forcing “www” in the URL was just the beginning. When they purchased your site, handturkey.com they got in over their heads. They hired you on as a consultant within weeks of the acquisition, and their first order of business was to lock down security. Handturkey.com has project management software, CRM, and ecommerce, after all. It seemed obvious that all the traffic in and out of the server needed to be encrypted.

“No problem.” You told them. You remembered that this can be accomplished with the mod_rewrite module in Apache. You tell them them that all they need is a few more lines in the .htaccess file in the root of handturkey.com, and that they should look like this:

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.handturkey.com/$1 [R,L]

This instructs the server to take any traffic on port 80 (HTTP) and forward it to 443 (HTTPS), forcing the traffic onto a secure channel. The Duch are grateful, to say the least. A week later you receive an iPad in the mail, a personal thank you from the dutch CEO, Filibert Broos.

Force WWW in a URL


Credit: Blogadilla

Congratulations, you did it! You’ve made yourself a website! Your dreams of creating a site all about hand-turkeys has come to fruition and it’s finally live. However, you can’t enjoy the launch as the irksome URL is pushing your obsessive compulsive buttons. As it stands, people can either go to http://www.handturkey.com, or just http://handturkey.com. You need clarity of bird-fingered vision. You also know that the Google sees those as two separate sites with duplicate content. This angers the Google. This makes the Google think you are a plagiary. You are most certainly not.

You can right this wrong by rewriting it. That is, you can rewrite the URL using a .htaccess file on your server as long as you are running Apache (there is also a Windows IIS module that emulates this). You decide you want to force everyone to use www.handturkey.com because it’s more professional. You create a file named .htaccess into the root of handturkey.com. Within this file you place the following:

RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.handturkey.com$
RewriteRule ^(.*)$ http://www.handturkey.com/$1 [R=301]

Et voila! Visitors are now forced to www if they don’t type it in. Google sees this and recognizes that both these sites are the same. It apologizes for insinuating you were a thief. It had a rough week and it totally took it out on you. You and Google bury the hatchet, and handturkey.com sells for a quarter of a billion dollars to a Dutch conglomerate.
