Caveat: I am experienced with Clojure, but a newbie at web development in
*any* language. I have recently begun going through the beta version of
the book "Web Development with Clojure"
http://pragprog.com/book/dswdcloj/web-development-with-clojure
Hopefully others with more web dev experience will respond with more
experience and knowledge to back up their answers.
In the simple web server code I've been working with in the book, it does
not make a connection to the database when jetty is started. Instead, a
new connection is made to the database every time a request is handled, and
the connection is closed before the response is sent back. All of the
examples I have seen so far handle all requests within a single thread, so
it does not hit the issue you have run into.
There are probably fancier techniques used when people are trying to
squeeze more performance out of their database interaction.
