    Brandon,

    	Thanks for the suggestion.  I hadn't even considered doing it that
    way, mostly because the existing service is pretty fast with no noticeable
    delays locally when an in-moo static document is delivered.  But we also do
    a lot of remote data access for many of the web requests.  First, these may
    take a minute or so to gather all the data from distant information services
    so any overhead in object creation is a small fraction.  Secondly, for these
    particular requests, the returned document is different (almost) every time,
    so its html has to be generated anew.

    	But I agree that cacheing already computed things is a big win when
    faced with high creation overheads.  The downside is that you then have to
    design and build a cache.  Luckily with OO, reimplementing our system this way
    would be comparatively easy.

    	Cheers,
    			Dave Van Buren
