Delta Encoding
In addition to standard conditional GETs the RSS Platform download engine supports Delta Encoding (for details, see Bob Wyman's post "Using RFC 3229 with Feeds") which allows the server to respond with only the feed items that are new or have been updated, thereby possibly reducing the response significantly.
So RFC3229 is supported by default in IE7... Good stuff for sure :)

Very nice article indeed and it shows I'm not the only wondering about
this. The A-IM idea is pretty neat and efficient apparently. I'll give it
a look.
Thanks,
