Performing HTTP purge request for cache/proxy servers

To purge the cache or proxy server as part of test setup (or teardown), one
can do something like this in Java:

I'm just wondering whether anyone has interfaced HTTP purge call with
JMeter via Beanshell or any of the other script pre/post processors or as a
plugin, etc.

I just figured it be useful to use what's available rather than reinvent
the wheel.

I don't have an immediate need for this but there might be a time in the
future where I might want to do this as part of load/performance testing
(to have clean starting cache state w/o having to go through server side to
purge cache).
