<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>

WP htaccess Control should now really be called WP htaccess and Rewrite Control. It provides an interface to customize the htaccess file generated by WordPress but also its permalinks (author, category, archives, pagination and custom taxonomies). Have a look at the screenshot for a clearer idea of the available options.
Features:
<ul>
<li>Customizing the htaccess file generated by WordPress;</li>
<li>Removing any custom taxonomy’s slug base from permalinks;</li>
<li>Removing the category base from permalinks;</li>
<li>Removing the author base from permalinks;</li>
<li>Customizing the Author Permalink Base;</li>
<li>Customizing Paginated Permalinks (translate the “page” word on permalinks to your own language);</li>
<li>Customization (and canonization) of the Search Permalink Base;</li>
<li>Creation of Category, Author, Tag and Custom Taxonomy based archives (ex: “http://your-site.com/category/stories/2010/12”, “http://your-site.com/author/admin/2010/12/page/2” and “http://your-site.com/tag/wordpress/2010/12”), this will also work if you’ve removed the base slug;</li>
<li>Maintenance mode.</li>
</ul>
Easy to use “Suggested htaccess” rules:

<h3>Known Issues</h3>
I still haven’t tested this under WordPress multisite, issues have however been reported.
<h3>Additional Credit</h3>
Removal of the category base is based on iDope’s WP No Category Base but extended so that it works with category archives (ie.: “http://example.com/my-category/2010/12”).
Search redirection is based on Mark Jaquith’s Nice Search but extended so that it works with custom search base (ie.: “http://example.com/search-base/search-term”).
<h3>Stable Versions</h3>
For WordPress versions above 3.9 use the plugin version 3.4.
For WordPress versions above 3.4 use the plugin version 3.3.
For WordPress versions prior to 3.4 use the plugin version 2.7.2.1.
