Imagine that you have a document in Knowledge folders that has an id of 229. This document will have three things
name description body
Using this url you can tell knowledge folders to spit out only the "body" portion of the document to the browser. This is useful for storing and viewing such things as javascript, style sheets, and master pages.
Structure of the url and parameters
Relative structure
/akc/display?url=DisplayNoteBodyURL&reportId=292
Absolute structure
http://www.knowledgefolders.com/akc/display?url=DisplayNoteBodyURL&reportId=229
Examples
See a document in its usual master page background
See the same document using DisplayNoteBodyURL
You can use this idea to see or retrieve master pages. Here is a sample master page.. You can then use the view source to copy master pages and create your own.
