Wikka Handlers

What is a Handler

Wikka handlers provide functionality that generally acts on an entire page or affects the wiki as a whole in some way. You could say that handlers "handle" something for the user, such as PageDeletionInfo deleting a page, modifying ACLInfo Access Control Lists (ACLs), or PageHistoryInfo showing page history.

Using handlers vs. using actions

ActionInfo Wikka actions affect a part of a wikka page, they are meant to generate content within the page. Actions are usually UsingActions inserted into a page along with all of the other markup. When the page is viewed/rendered, the action is "executed" and its output is displayed.

Wikka handlers, on the other hand, are not inserted in the page body, but are invoked when you submit a form or click on a menu link like "Page History". They can be manually invoked by appending to the URL of a page the name of the handler preceded by a slash. For example, to switch from the formatted view to the edit view of this page, just append to the URL displayed in your browser address field /edit.
