[Zope] Cached Variables

[calisp at gmail.com]

Hi,

I am developing an application that is a front end to an RDBMS. 
Sometimes, when loading a page, several scripts get called that all
require the same information from the database.  It would obviously be
costly for each script to call the same ZSQL method.  My method for
avioiding this senario is...

Get the scripts to call another script that is a wrapper to the ZSQL
method.  This wrapper script returns context.REQUEST[value_name] if it
exists or, if it does not exist, executes the ZSQL method, stuffs the
result into REQUEST[value_name] and then returns it.

I am not convinced that this is the right way of dealing with this
situation however.  Is there a better way?

Thanks,

Calisp
