I can do this.  Is there a set of tests that people would like to see?
I think we should concoct a test plan, albeit a very basic one.

Is there a squidbench?  squib for short? Maybe it could start by either fetching a digest or using one as input?  Or just use a list of urls from an access.log?

If we don't have a level SUT (system-under-test playing field) we can at least have a level load-generator.  The fewer variables the better.

Are there redhat packages for 2.7?
