Redirection to www. using htaccess

Some of the errors.

This code does not redirect host requests with appended port name, and therefore allows Duplicate Content.

Code: Select all

RewriteCond %{HTTP_HOST} ^yoursite\.com$ [NC]
RewriteRule .* http://www.yoursite.com/ [L,R=301]

Consider what happens if example.com/index.php is requested in the next code. The first ruleset redirects to http://www.example.com/index.php and the second ruleset creates a second redirect to http://www.example.com/. You should avoid creating a redirection chain.

Code: Select all

RewriteCond %{HTTP_HOST} !^www\.yoursite\.com$
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [R=301,L]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ HTTP/
RewriteRule index\.php$ http://www.yoursite.com/%1 [R=301,L]

The code also does not redirect index URLs within folders. It can only do the root.

The "referrer" code is horrible, likely able to be replaced with a single line of code. There are multiple errors in it, not least the lack of escaping on literal periods. Additionally, code like that should go ahead of all the other stuff. Why redirect some requests and then block them. Why not do the blocking first?

There are replacement default .htaccess files for Joomla 1.5 http://joomlacode.org/gf/project/joomla ... m_id=25090 and Joomla 1.6 http://joomlacode.org/gf/project/joomla ... m_id=22425 awaiting commit. The new files fix a number of problems.
