<h4>Redirect manager</h4>
Create and manage redirects quickly and easily without needing Apache or Nginx knowledge. If your WordPress supports permalinks then you can use Redirection to redirect any URL.
There is full support for regular expressions so you can create redirect patterns to match any number of URLs. You can match query parameters and even pass them through to the target URL.
The plugin can also be configured to monitor when post or page permalinks are changed and automatically create a redirect to the new URL.
<h4>Conditional redirects</h4>
In addition to straightforward URL matching you can redirect based on other conditions:
<ul>
<li>Login status – redirect only if the user is logged in or logged out</li>
<li>WordPress capability – redirect if the user is able to perform a certain capability</li>
<li>Browser – redirect if the user is using a certain browser</li>
<li>Referrer – redirect if the user visited the link from another page</li>
<li>Cookies – redirect if a particular cookie is set</li>
<li>HTTP headers – redirect based on a HTTP header</li>
<li>Custom filter – redirect based on your own WordPress filter</li>
<li>IP address – redirect if the client IP address matches</li>
<li>Server – redirect another domain if also hosted on this server</li>
<li>Page type – redirect if the current page is a 404</li>
</ul>

Hyper Cache is a cache plugin specifically written to get the maximum speed for your WordPress blog.
It can be used in low resources hosting as well on high end servers.
Hyper Cache is purely PHP and works on every blog: no complex configurations are needed and when you deactivate it no stale settings are left around.
NOTE
Mobile detection server side and serving different content to mobile and desktop device is now obsolete. 
Every modern WP theme deals with mobile/desktop contexts using the media queries, progressive enhancement and so on. 
So I don’t see the need to keep the mobile/desktop cache separation and all the overhead in the plugin. The feature will be removed as version 3.5.
Short list of features:
<ul>
<li>Mobile aware: double cache for desktop and mobile site versions</li>
<li>HTTPS ready</li>
<li>Mobile theme switch option: change the theme on mobile device detection</li>
<li>Able to serve expired pages to bots to increase the perceived blog speed by bots</li>
<li>Manages compression even on the fly for non cached pages</li>
<li>Lots of configurable bypasses: matching cookies, matching urls, user agents, …</li>
<li>Comments aware: is able to serve cached pages even to visitors who commented the blog (perfect for blog with great readers paritipation)</li>
<li>Cache folder can be moved outside your blog space to exclude it from backups</li>
<li>Controls over cache cleaning on blog events (post edited, comments, …)</li>
<li>Autoclean to controls the cache used disk space</li>
<li>CDN support</li>
<li>Other special options</li>
<li>Response header signature to check the working status</li>
<li>bbPress specific integration</li>
</ul>
