For now, leave all of these entries as is, they are good,
reasonable defaults. That's all there is to setting up a cache

A description should be given of how the REQUEST variables
are used as keys (eg. how to use form data/query strings
as part of the key).
/path/to/url?month=Jan should not hit /pth/to/url?month=Feb in the cache.

Normally query string parameters can be placed directly into the
"REQUEST variables" area. For example, with the following request:
if the "REQUEST variables" area has a single line "month" (instead of
the default "AUTHENTICATED_USER"), then
a single "Path" will show up in the Statistics page; however, there
will be a different entry accounted for in the "Entries" column
of the statistics page: one for each distinct month value that
has been cached. No distinction will be made upon the "day" query
string (unless an additional line is given for "day" in the "REQUEST
Note that if a Zope directory houses an "index_html" file, and the
URL does not explicity give the "index_html" (i.e. http://www.zope.org/path?month=xxx instead of
the query string will not be able to serve as a key for the cache manager.
Therefore, if you want to cache index_html, keying on query strings, then
you must give fully qualified paths to the .../index_html object rather
than assuming index_html as the default.
