While you could work around this with an iRule, I think that just making a configuration change around that bug would work too. In my tests, adding:

to the profile (so it isn't empty anymore, thus avoiding the CR) makes the minimum size start working.

While this is an excellent idea, this did not work for me...

I added to the profile exclude list, disabled the VIP, reset manually from ramcache, checked ramcache to make sure it was empty, re-enabled the VIP, and my page with content-length= 6 gets cached right away.
