RULE vs MGET

Hi Patrick,

What are the advantages of MGET over the RULE technique (e.g. add
'.meta' onto the end of the URI) for getting metadata about the
resource. I don't think I've heard any arguments to persuade me that
this isn't a workable solution. (other than it's a bit ugly).

Advantages of RULE over MGET:

 - no change required to web infrastructure (proxies, caches, webservers)
 - no change required to http client libraries (even the broken ones!)
 - simple to deploy 
        - e.g. can be done by putting text files in an existing
        public_html dir

These seem pretty big advantages to me.

Many thanks,

Phil
