[Zope-dev] RAMCacheManager and gzip

Thu, 6 Dec 2001 21:30:29 -0000

Just to let you know, I am looking at patching ZServer using my PatchKit
product to do "Content-Encoding: ..." stuff... anyone interested in testing
when I get it running?

(Probably a couple of days before I get a running version...)
