HTTP 303: http:// instead of http://www results in Loop / 303


I have a Joomla! 1.5.23 website running Artio for SEF urls. Complete configuration:

  • JoomSEF3 3.9.5
  • Virtuemart JoomSEF extension 2.1.1
  • Joomla! 1.5.23
  • Virtuemart 1.1.9
  • Joomfish 2.0.4

I have told Artio (SEF component) to use www urls only. Somehow when I go to a http:// url without the www the browsers hangs. Firefox 11 tell me

The page isn't redirecting properly
Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

Telling Artio not to handle the www non-www stuff and purging the urls still gets me the same issue going to a non-www url. Firebug shows me a status 303 - see other - in both cases (both Artio settings) . Makes me think it is a .htaccess issue or a DNS issue. Here is the .htaccess:

I never had a 303 before. How can I make www-less urls work again?

Update 1

When I uncommented

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]

I got a 301 and could not reach the site using a www url

Update 2 Doing some testing this week together with Artio, the makers of the SEF component. Nobody here seems to have a clue so this seems to be the best way to go.


Solution

  • Good people at Artio found the issue for me: "... the problem was caused by „Use 302 redirect“ option being enabled in System – Jfrouter plugin. Non-www domain seems to be correctly redirected to www if this option is disabled." All good now.
