Hello all,

I made a proposal in January about providing a conditional GET
capability in HTTP.  It involves accepting a Last-modified header
in an HTTP request and sending the document only if the Last-modified
date of the document is more recent than the one in the request.

The full proposal is now available at 

      http://www.ics.uci.edu/WebSoft/caching.html

I was wondering whether any of the server authors are planning on
including this feature in future versions?
