I followed the instructions in the comments of the .htaccess file located in the root of my Drupal 6.22 web site (lines 93-94 below).

This configuration does not work. Any idea where I might be going wrong?:

#

#

# Protect files and directories from prying eyes.

  Order allow,deny
</FilesMatch>

  # (http://example.com/... will be redirected to http://www.example.com/...)
  # adapt and uncomment the following:

  # Modify the RewriteBase if you are using Drupal in a subdirectory or in a

  # If your site is running in a VirtualDocumentRoot at http://example.com/,

  RewriteCond %{REQUEST_URI} !=/favicon.ico
  RewriteRule ^(.*)$ index.php?q=$1 [L,QSA]

Thank you.

Looks like you forgot to escape second . character. It should be:

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

On another hand -- . represents ANY character, so should work just fine.

In any case -- this is easier approach as no regex is involved:

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

  • Thank you also LazyOne, but this doesn't work either.

  • OK, few ideas here. Let's try it one by one. For testing purposes put these rules on the very top and make RewriteEngine on your very first line. Maybe you behind some sort of proxy .. or PHP is run somehow differently (don't know), but lets try this: 1) Remove $ character so the rewrite looks like this: RewriteCond %{HTTP_HOST} ^example\.ac\.uk [NC] and RewriteRule ^(.*)$ http://www.example.ac.uk/$1 [L,R=301] -- this should katch situations when you also have port number as part of HTTP_HOST.

  • 2) Please use a Firebug for Firefox, "Net" panel or any other similar tool) to confirm that 301 redirect actually happens (or not). 3) let's do other way around -- and rewrite all NON www.example.ac.uk to this domain: RewriteCond %{HTTP_HOST} !^www\.example\.ac\.uk$ [NC] RewriteRule ^(.*)$ http://www.example.ac.uk/$1 [L,R=301]

  • 4) Create simple php file echo.php and put it into root folder: <?php phpinfo(INFO_VARIABLES); ?> Add this rule just below RewriteEngine on: RewriteCond %{REQUEST_URI} !^/echo\.php RewriteRule (.*) /echo.php?host=%{HTTP_HOST}&url=$1 [L]. Please comment out ALL other rewrite rules (preferably all directives altogether). Now have a look at the variables dump, especially at QUERY_STRING

  • The redirect works when accessing the site from home, which suggests that the network configuration at work is to blame. Internet traffic may well be routed through a proxy. Why would this configuration prevent the redirect from working? With hindsight, I should have tried to access the web site from my smartphone or something first. Lives and learns! Thanks for all your help LazyOne.

might be missing another \

RewriteCond %{HTTP_HOST} ^example\.ac.uk$ [NC]

should be

RewriteCond %{HTTP_HOST} ^example\.ac\.uk$ [NC]

  • Thanks for suggestion. I tried escaping \.uk, but still no joy.

  • are you sure mod_rewrite is enabled?

  • Yes. # apache2ctl -M confirms rewrite_module (shared) is loaded.
