Automatic www/non-www URL handling

When you set up a website, there are two ways people can access it: www.yourdomain.com, or just yourdomain.com. This creates a couple of problems. First, unless you've set the site's cookie domain to .yourdomain.com, when someone logs in at yourdomain.com they won't be logged in at www.yourdomain.com -- which leaves them confused if they end up on the other version from a link they found somewhere. Secondly, search engines don't like the duplication.

The solution for this has always been to add redirection into the .htaccess file to redirect www URLs to their non-www equivalents or vice versa. Many of you have done this in WSN using the extra .htaccess content option in the SEO settings.

The latest WSN 10 beta adds automatic handling of this situation, whenever URL rewriting is enabled on a site. It checks the directory url value to see whether you want www or not, so you can change it either by changing the directory URL at Admin -> Settings -> System Configuation or by changing the selection at Admin -> Settings -> SEO -> Domain Format (which will in turn update your directory URL for you). WSN writes the appropriate redirection rules to the .htaccess automatically.

Having a duplicate redirection (one you set in the extra .htaccess content as well as the new automatic redirection) shouldn't be a problem, works fine in my tests, so you don't have to change anything -- but can feel free to remove any redirection you added whenever you're ready, for clarity.

A Day in the Life of a Programmer

The reality of being a programmer is somehow portrayed on this GIF. This situation merely happens when a newbie programmer seeks help from a fellow programmer.

Sometimes, it is also a challenge for an expert programmer to extend help to our fellow programmer; but yes, reaching out a hand should never be a worry.

I hope you can relate on this GIF, and gracefully extend your expertise to help or teach those who are in need of you.

Though programming is hard to understand and to solve, it is always fun; and can even be more enjoyable with hands helping each other.
