The "Document_Update_Handlers" page has been changed by PaulBonser.
The comment on this change is: When using update handlers, there's no document 
posted by the user. The document comes directly from the DB, based on the 
requested ID..

  == Basics ==
  
- CouchDB (0.10 and up) has the ability to allow server-side processing of an 
incoming document before it's committed. This feature allows a range of use 
cases such as providing a server-side last modified timestamp, etc.
+ CouchDB (0.10 and up) has the ability to allow server-side updating of a 
document without the usual GET-modify-POST cycle, or server-side creation of a 
new document based on parameters sent by the user. This feature allows a range 
of use cases such as providing a server-side last modified timestamp, updating 
individual fields in a document without first getting the latest revision, etc.
+ 
+ It's important to note that and update handler doesn't need to have an entire 
document sent to it, as it will be passed the server's current version of the 
requested document. In fact, any parameters passed to an update function, other 
than the document ID, have to be handled manually by the update function itself.
