   If I create an iphone page and do an autoredirect to it, how can I link back to the main site? I’m using a joomla site, so all pages on the site use the index.php?pagename idea, so whenever I try to access another page on the site, I’m taken back to the iphone specific home page.

   I tried implementing this code but I got an error when I tested on my iphone:

   Safari cannot open page because too many redirects occurred.

   How do I fix this? Thanks!

   I’m getting the same issue on the iPhone… too many redirects…

   I would love for this to work because of the sheer simplicity!

   Any fix on this?

   hi, you forgot to add:
   
RewriteEngine on

   in a first line. It may be required if it’s not globally on

   Haha no bodies understand how to use it ….

   If you have a too many redirections that means you try to redirect the user to the same domain with the same htaccess and here the loop!

   The solution is too redirect the user to anohter domain with no htaccess or to redirect the user to an mobile.html page and to add a condition at the top of your htaccess.

   I cannot post the complete code due to my company … but the idea is here

    @Tom,

    I see the issue with the redirect loop. The page I am trying to forward to is using the same htaccess.

    What is the condition syntax to “add a condition at the top of your htaccess.”

    Thanks.
    Here is the redirect:

    #redirect mobile browsers
    RewriteCond %{HTTP_USER_AGENT} ^.*iPhone.*$
    RewriteRule ^(.*)$ http://www.davidgregorywells.com/social [R=301]
    RewriteCond %{HTTP_USER_AGENT} ^.*iPad.*$
    RewriteRule ^(.*)$ http://www.davidgregorywells.com/social [R=301]
    RewriteCond %{HTTP_USER_AGENT} ^.*BlackBerry.*$
    RewriteRule ^(.*)$ http://www.davidgregorywells.com/social [R=301]
    RewriteCond %{HTTP_USER_AGENT} ^.*Palm.*$
    RewriteRule ^(.*)$ http://www.davidgregorywells.com/social [R=301]

      I created a subdomain(mobile.mydomain.com) that pointed to a folder (mydomain.com/mobile)

      I modified my .htaccess file in my domain’s root directory with the code above.

      I added a .htaccess file in the subdomain folder (mydomain.com/mobile)
      with one line.

      RewriteEngine off

      That fixed the redirect loop for me.

    this code seems to work for me for the iphone at least.

    RewriteEngine on
    RewriteCond %{HTTP_USER_AGENT} iPhone
    RewriteCond %{REQUEST_URI} !^/iphone/
    RewriteRule .* /iphone/ [R]
