No-blank-page plug-in?

Does anyone know of a "no blank pages" plug-in?  What I'm looking for 
is a Blosxom plug-in that will, if a URL addresses a date range that 
contains no articles, or an article-specific page that doesn't exist, 
causes some administrator-defined default redirection?

For example:

If http://host.domain.tld/blosxom.cgi/2008/06/01 doesn't contain any 
articles, or http://host.domain.tld/blosxom.cgi/no-story.html doesn't 
exist, then a meta-refresh line could be added to head.html to 
instead redirect to some other URL.  Normally, Blosxom would just 
display a page with no articles.  Another alternative would be a 
default story file that Blosxom would insert as if it was the story 
requested, in a file that looks just like a Blosxom story.

Does such a plug-in exist?
