Absolutely. A "checkout" is simply a series of HTTP GET operations. The
cache is *definitely* going to hold onto those.
It could probably do diffs, but I'll have to get some stuff implemented
because I'm not exactly sure how we'll be implementing the diff draft
(referenced from the webdav-design.html document in CVS). Specifically, that
should have some "Vary:" headers which would help control how the proxies
will cache and under what "key", if you will.
But the bulk: big time.
Just think... an SVN repository getting picked up and shared across the
akamai caching network! Woo!
:-)
