[Web4lib] Need efficient way to post "library closing" message

[Tom Keays]

SSIs add no significant processing time with today's server
technology. Every single page on our library website has one or more
SSIs (footer, navigation). They are the simplest solution for what you
want to do because they are easy to maintain (edit a single text file)
and don't require anything special at the user's end (display happens
at the server end rather than in the browser).

If your server isn't capable of SSIs, Bill's solution of iframes is a
good one, but is somewhat browser dependent. I wouldnt' worry about it
though as most modern browsers support them and it is an easy way to
pull content into a page.

Javascripts that display RSS feeds are, on one hand, easy to maintain
(usually a by-product of a news blog) and, on the other, extremely
vulnerable to user preferences -- i.e., if the user has javascript
turned off, the message isn't displayed.
