[Ops] UserAgentUsage

[Mark Taylor]

Dear Ops,

at the recent Interop we had some discussions about how we can/should
use the User-Agent HTTP header to allow service operators to identify
requests originating from things like validators as distinct from
user science requests.  Following this, I have drafted some text
on this wiki page:

   http://wiki.ivoa.net/twiki/bin/view/IVOA/UserAgentUsage

I think it more or less reflects what we concluded at College Park,
but there are a few details and open questions I've filled in.
If you're interested in this topic, please take a look and
post comments here or to me, or just edit the wiki page.

If people are in agreement with this approach, I'll try to
implement it in my clients, and we can talk about whether it
makes sense to issue it as an IVOA Note.

Mark
