[wp-hackers] Controller Implementation

[Brian Layman]

Sure.. Maybe this will help..  If I am still not making sense, just nm it's
been a long day. It makes sense to me at least :D

This was a basically a reiteration of your initial statement in #12935:
<blockquote>
  As WordPress grows into a proper CMS with MultiSite and Custom Post Types
and Custom Taxonomies there are frequent opportunities for URL conflict that
didn't occur as often with just Posts and Pages. 
Here's a simple example, let's say a company uses WordPress for their
website and they offer development services as well as training on their
website: 
http://example.com/services/vmware/
http://example.com/training/vmware/
</blockquote>

two?
When you are creating a new post, if there is a conflict, the permalink/slug
is modified to prevent the conflict in the first place (by adding a -2 or
whatever). If the goal is to create a system that can quickly identify the
globally unique target for an URL, I would seem that there is a tie in to
this functionality. It should be able to tell you if the proposed permalink
would an existing target.

When you say "router", do you mean the existing WP_Rewrite >or the WP_Routes
I was proposing?
You=Jacob, as I was replying to his post to the list and the Router &
controller concepts as discussed there-in. You'd not replied yet when I hit
send.

I added this as I was thinking about how a blog admin could choose a new
permalink structure and inadvertanly cause many urls to no longer be
globally unique.

Hope that helps...
