[Zope] Superfast PageTemplates: Call for expertise

[sean.upton@uniontrib.com]

I think, in theory, you can do ESI in Zope now, you just need to use a
patched Squid in front of Zope, use well-formed XHTML with embedded ESI, and
set appropriate HTTP headers (Surrogate control header) manually so that ESI
is parsed on the client-connection end of Squid.  I haven't used this, but I
bet this would work.  I think the only requirement is well-formed xml for
your templates.

What future Zope versions would theoretically add is a way to detect esi
usage in a ZPT and set the header for you automatically.

You could probably do 90% of that by stuffing layout fragments into RAM 
Caches and Session data... and then you could assemble the whole thing on 
the fly using DTML... oh, wait. :-)

More seriously, it'll be great when the ZC/Squid ESI project becomes 
available.  That should serve this purpose nicely.
