Redirect all to a www page

In apache, we can redirect pages having no www to its www counterpart without manualy adding the www on the url by using mod_rewrite. Like for example, try to type in my url as tildemark.com on your browser's address bar, hit Enter and automatically you will be redirected to https://tildemark.com. This is useful to avoid duplicate caching of pages and the division of your pages' PR.

We need to edit our .htaccess file to add the 301 redirect.

# .htaccess file
# we need to check if mod_rewrite has been enabled, 
# by default its not

  RewriteEngine On
  RewriteCond %{HTTP_HOST}       ^tildemark.com
  RewriteRule (.*)               https://tildemark.com/$1 [R=301,L] 

Replace tildemark.com to your respective domain name. here's a mod_rewrite cheatsheet from ilovejackdaniels.com

Notes:
301 is an http status code meaning permanent redirect
.htaccess files should be placed on the root directory
PR is PageRank
