[Zope] Yet another simple question

[Peter Bengtsson]

If a ZSQL Method *fails to cache* its result (internally by Zope, not by
HTTP caching),
when it should,
what could then be the reason?

I have read a few posts on this in the archives but I see no clear
solutions.
It seems to be that if the SQL string from Zope to the database adapter is
one whitespace different it spawns a new db request.
We think our SQL is the same all the time, but it fails to cache and the Z
SQL Methods slow down our site.
