问题
I started by using the method described here in order to create a Mobile redirect, and it works perfectly.
What I need to do next, however, is prevent it from happening on any page other than the homepage. In other words: If the user loads the homepage from a mobile device, the redirect should happen - but if they load any other page from a mobile device, the redirect should not occur.
I'd love any advice the community might be able to provide as to how to accomplish this effectively.
回答1:
You need to redirect by checking out the User-Agent:
Mobile website redirection based on user agent
or on PHP:
<?php
$useragent = $_SERVER['HTTP_USER_AGENT'];
//mobile example
if( strpos($useragent,"Blackberry") ) {
header("Location: http://m.nickyeoman.com/");
}
//css example
if( strpos($useragent,"wii") ) { ?>
<link rel="stylesheet" href="/css/wii.css" type="text/css" media="all" />
<php } else { ?>
<link rel="stylesheet" href="/css/global.css" type="text/css" media="all" />
<php } ?>

I just had to add
[OR]
RewriteCond %{HTTP_HOST} ^(mydomain\.com|www\.mydomain\.com)$ [NC]
That was it. So, in the end, it looked like
# Check if we're not already on the mobile site AND just going to the homepage
RewriteCond %{HTTP_HOST} !^m\. [OR]
RewriteCond %{HTTP_HOST} ^(mydomain\.com|www\.mydomain\.com)$ [NC]
# Can not read and write cookie in same request, must duplicate condition
Make sure you get the [or] in there too. Hopefully my newb advice will help someone someday
