  - Do you mean SQUID is intended to act as an accelerator for
this webserver ?

   One way to configure an accelerator , is to define it as a cache_peer
in squid.conf , and use :

              never_direct allow all

(too).

When defining a 'cache_peer' you have an option :

               max_conn

which limits the max. number of connections, SQUID is allowed to
launch to the peer, in this case your webservice(database-webserver).

Perhaps this could help. It would be more friendly, seen from the end user
point. How it trenches the user-side load, is not immediately clear
for me at the moment.

Cache.log, observing and access.log, would be first items to follow
up too I guess.
