We have 2 x CS11154's and 2 x CE560 configured for reverse proxy cache as a front end to a web server. I notice from time to time that connects to the caches during a show service summary spiral upwards. We also register lots of service hits on the eql cacheable content rule.

When you look at the transaction logs on the CE's you see a HTTP requested for an object thats is constantly repeating over and over as a cache MISS. 1st time it was a pdf second time it was a gif, both of which are cacheable.
