New life to this Field!

Improved update for 2.3 and split redirect functionalities into a separate extension. This is so simple now :)

 * Release date: 30th March 2012
-* Version: 0.4
+* Version: 0.5
 
 This is based on the [Entry URL Field](http://github.com/nickdunn/entry_url_field/) by Nick Dunn.
 
 
 ## Use
 
-Let's say you have an url structure like `post/category-handle/post-id`.
-You don't want to rely on services like bit.ly but that url is just too long. Time to give this a try then!
-
-The first thing you'd want to do is to add the field to your `Post` section.
-
-There's a `Url` field which should reflect your url structure so, in this case, 
-we're going to populate it with a value of `post/{entry/category/item/@handle}/{entry/@id}`.
-
-It's pretty straightforward, you just use xpath expressions as you normally do when building `@href` links.
-That's a relative url, so `$root` will be prepended automatically.
-
-
-## Filtering
-
-Ok, this is cool so far, but you need a way to specify if and how the redirect should happen.
-This is done through datasource filtering.
-
-Symphony 2.3.1 supports page params in index page, which is exactly what you need for this extension to work.  
-Simply add a parameter to your index page (let's call it `r`). Now create a datasource which filters by 
-this field with `{$r}` as value and attach it to the index page. Whenever a page isn't matched (you don't have 
-page handles like `55u`, don't you? :D), Symphony will fallback to the index page and execute the datasource.
-If a match is found, it will automatically redirect to the url specified in the entry. Cool stuff.
+This field just stores an unique alpha-numeric short identifier for each of your entry.
+It used to perform redirect too, but I felt that would have required an extension of its own because there are 
+quite a few use cases that have to be adressed.
