Subdomain for a mobile site?

  • Posted September 3, 2014


I have an ubuntu droplet running wordpress.

I developed a desktop and mobile theme for my Wordpress site and switch between the two using a wordpress plugin that detects the device the user is on and loads the appropriate theme accordingly. The only problem is this conflicts with varnish; since the URL is the same for both mobile and desktop browsers, sometimes desktop viewers will see the mobile site (and vice versa).

I’d like to setup a subdomain,, that gets loaded if the user is on a mobile device. But obviously I wouldn’t want to run two sites as this would cause headaches in managing the data.

What’s the best way to do this?

What is the WordPress plugin that you are using to detect the device size? Does it support redirecting to a subdomain or are you looking for an entirely different solution?

There are also other ways that you can solve this problem. Using a more responsive theme that adapts to different form factors is becoming the standard solution. You could also look into something like Varnish Mobile Detect which will use a different backend based on the browser’s UserAgent.
