I did not address this originally because my original post covered a different 
senario. It now seems necessary, because the cost - money cost, for the real 
world - of ignoring cached images is too great and because the overhead of 
parsing the html files on the server side is also a drawback.

I was trying to get the HTTP spec to look at, but CERN is down (again) and the 
HENSA cache doesn't have it, currently. Oh well. I was about to find an unused 
character to join the urls with. This is analogous to using + for space when 
sending queries with get.

Lets say & is unused. A possible syntax would be

  GET multi&url1&url2&url3 HTTP/1.1

A problem I see with this - is there a max line length for a GET command?

Failing which we may be into using POST....

Sorry about the vagueness, folks; I must print out the spec next time it becomes 
available.
