Guys,
Today I had a bad time with a non-www to www redirect on a Django site.
Since I had worked many PHP applications, I tried apache redirect and mod-rewrite options with no luck. After some googling, I came to know that the mod-rewrite option won’t work with Django applications.
The only solution is to give the following in the server_settings.py configuration file of the Django application.
PREPEND_WWW = True
Reload apache, then try the URL.
After enabling this your site will automatically redirect from example.com to www.example.com for any URLs.
Bonus: The normal mod_rewrite option for PHP
Redirect non-www to www:
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]
Redirect www to non-www:
RewriteEngine on
rewritecond %{http_host} ^www.domain.com [nc]
rewriterule ^(.*)$ http://domain.com/$1 [r=301,nc]
