CacheFu generates VCL files now?

In any case, discussions of Zope/Plone and CacheFu are not directly 
appropriate here, I doubt the Varnish developers know much about it.

I'm using Varnish 1.0.4 with CacheFu 1.1 and Plone 3.0 on my website. 
Varnish 1.0.4 will only compile on Linux, BSD and similar (i.e. not on 
OS X) so be aware of that.

Lots of people (i.e. everyone I've spoken to) have reported problems 
with Varnish 1.1.1 in front of Plone (though it's not directly a Plone 
problem, since accessing it directly does not exhibit the same behvaiour 
- it could of course be some bad cache headers, but I've been unable to 
confirm that). I experience periodic "dropped" requests or requests that 
never complete (see other thread on this list). I'm really hoping 
someone can get to the bottom of this, since being stuck on an older 
version is not ideal. :-(
