:) wait a minute

GET / HTTP/1.1
Host: www.example.org
Capabilities: <http://example.com/acmeCom/new/shiny/browser/23>

What is happening when example.org meets the client

1.  for the first time, example.org might download the URI which might be huge. It means big latency for replying to the client with the right content.

2. to avoid that example.org will be clever, they will cache the capabilities file and do negotiation on the URI becoming an ID.

3. Some business will start by selling list of URIs and capabilities files (the thing which is happening), create Databases.


* Some business will be abandoned. Databases will not be updated. Future fail
* The cache system will not be maintained. future fail.
* Some scripts will use the URL-ID (new useragent string) to block, filter, redirect.

Basically exactly back to the same situation we have today.
