Overview:
When users express their own business logic, often written in the code relatively smoothly, under such conditions apply, you can write a different tag url passed to this url, returns different results, returns an empty expressed smoothly.
Example: Set a http in the implementation of content in: //myserver/Do.aspx DoType = aaaaa, create a Do.aspx process according to DoType mark this different content?.
