Redirecting between a desktop-browser site and a mobile site

Question

My company is inheriting a site built by another party in CQ5. This site is intended to be viewed on a desktop browser. We are tasked with building a mobile site for it. Our creative department would like the user's browser to be detected, and if the user requests a page on the desktop site from a mobile browser, they would be redirected to the mobile site. Is there any way to do this on the server side without disabling caching on the site?

Answer 1

true
nevertheless, you need it in places for uncached requests. additionally you have the options of:
- javascript redirect (allows you to build an "opt-out" for the user, i.e. the user wants to stay on desktop regardless of mobile device, via cookie)
<script language=javascript>
<!--
if (navigator.userAgent.match(/mobile/i))
   location.replace("http://mobile.myurl.com");
-->
</script>
- apache configuration redirect
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^.*(mobile).*$ [NC]
RewriteRule ^$ http://m.example.com/ [L,R=302]
</IfModule>
dom.
