Over the course of the past couple of months there have been a number of questions that popped up on the mura forums regarding URL masking and redirects. I found myself copying & pasting the same snipit of code for a handful of different users and finally decided that I would take a couple extra minutes to turn it into a plugin and add it to the mura app store.
The concept is incredibly simple. Once the plugin is installed you can navigate the extended attributes of any page and define an "Alternate URL". This can be used for creating marketing friendly short URL's, or setup simple 301 redirects to map old links to new pages.
For example if you have a page like this is mura: http://www.myDomain.com/my-services-section/my-special-services/cool-service/
You can just setup "cool" as an alternate URL so the link will look like this: http://www.myDomain.com/cool/
You can also define if you would like to do a standard redirect, 301 redirect, or no redirect but pull the correct content. I should say that it is important to note that this plugin doesn't use the 404 event handler to manage these redirects. That way any other plugins that tie into the 404 handler for logging ect will not be fired because this isn't a true 404. Also, by doing the redirect at the top of the lifecycle it improves performance on these requests.
You can find the plugin in the app store here: http://www.getmura.com/app-store/apps/url-tools1/
And feel free to fork, feature request & log issues here: https://github.com/gregmoser/muraURLTools
Please let me know if you have any ideas for improvements, I am happy to build out additional functionality into this simple plugin.
