[Zope] Zope caching method results??

[John Toews]

I have an external method that is using a class I've written. The class
uses another module (dbxml for the Berkeley XML database).

It _appears_ as if Zope is caching function results from the dbxml
module. The data doesn't change, but the memory address does.

tmpXmlResults = self._manifest.queryWithXPath(resourceXpath,
self._manifestcontext)

The code runs perfectly if run outside of Zope simply on the command
line.

Is there any sort of caching that Zope does of non-product Python
objects? Or function results? Etc.?

Thanks,
John toews
