how to make polipo cache everything

Thanks to Moroni for the help so far.
I'm trying get polipo to cache all my requests until I explicitly delete them.
Right now when I do a request for http://www.yahoo.com/ it saves
something in the www.yahoo.com folder but it deletes it and saves a
new one when I make the request again. Here's what my config looks
like:

proxyAddress = "127.0.0.1"
proxyPort = 8118
allowedClients = 127.0.0.1
allowedPorts = 1-65535
proxyName = "localhost"
chunkHighMark = 33554432
diskCacheRoot = "/cache"

Thanks for the help.
