Brian, I would actually need an alternate page if I DO find any hits.  I'm
sure that's what you meant.  ;-)  Anyway, the buffering is certainly a
problem.  While I'm not developer, I can't see any way around this.

Brian, I'm a little confused by this.  How does this avoid the buffering
problem?  My original thought was to do exactly what you suggest.  I was
thinking of scanning for keywords and, upon a hit, replacing all the
characters in the page with a simple text message.  However, this has all
the buffering and performance problems you mentioned in your post.
