Easily and safely manage your site’s redirects the WordPress way. There are many redirect plugins available. Most of them store redirects in the options table or in custom tables. Most of them provide tons of unnecessary options. Some of them have serious performance implications (404 error logging). Safe Redirect Manager stores redirects as Custom Post Types. This makes your data portable and your website scalable. Safe Redirect Manager is built to handle enterprise level traffic and is used on major publishing websites. The plugin comes with only what you need following the WordPress mantra, decisions not options. Actions and filters make the plugin very extensible.
There are no overarching settings for this plugin. To manage redirects, navigate to the administration panel (“Tools” > “Safe Redirect Manager”).
Each redirect contains a few fields that you can utilize:
This should be a path relative to the root of your WordPress installation. When someone visits your site with a path that matches this one, a redirect will occur. If your site is located at
http://example.com/wp/ and you wanted to redirect
http://example.com, your “Redirect From” would be
Clicking the “Enable Regex” checkbox allows you to use regular expressions in your path. There are many great tutorials on regular expressions.
You can also use wildcards in your “Redirect From” paths. By adding an
* at the end of a URL, your redirect will match any request that starts with your “Redirect From”. Wildcards support replacements. This means if you have a wildcard in your from path that matches a string, you can have that string replace a wildcard character in your “Redirect To” path. For example, if your “Redirect From” is
/test/*, your “Redirect To” is
http://google.com/*, and the requested path is
/test/string, the user would be redirect to
This should be a path (i.e.
/test) or a URL (i.e.
http://example.com/wp/test). If a requested path matches “Redirect From”, they will be redirected here. “Redirect To” supports wildcard and regular expression replacements.
“HTTP Status Code”
HTTP status codes are numbers that contain information about a request (i.e. whether it was successful, unauthorized, not found, etc). You should almost always use either 302 (temporarily moved) or 301 (permanently moved).
- Redirects are cached using the Transients API. Cache busts occur when redirects are added, updated, and deleted so you shouldn’t be serving stale redirects.
- By default the plugin only allows at most 250 redirects to prevent performance issues. There is a filter
srm_max_redirectsthat you can utilize to up this number.
- “Redirect From” and requested paths are case insensitive by default.
- Developers can use
srm_additional_status_codesfilter to add status codes if needed.
Install the plugin in WordPress. You can download a zip via GitHub and upload it using the WordPress plugin uploader (“Plugins” > “Add New” > “Upload Plugin”).
