[Zope] Storing published objects (?)

Hello All, I'm not sure if the title accurately reflects what I want to do. I have a DTML method that uses a number of other objects and generates HTML code (the usual). What I'd like to do is assign/save the HTML code the method generates. I'd like to save the HTML as a BLOB in a database, and next time a user calls up a particular report, if the source data hasn't changed, publish the pre-rendered HTML. The underlying SQL queries are complex, the data doesn't change often, and I think this may be the best way to lighten the burden on the DB. Is this possible? If so, how would I go about accomplishing this? Perhaps there's a better way of accomplishing this? Thanks in advance. Regards, Samir
