I seem to have stumbled upon a few bugs with the Cache Inspector Web UI - I'll bundle them in this ticket, for your annoyance
First of all, the titles of the lookup pages seem to have <font> and </font> in them, which should probably be fixed - see f.x. http://dallas.awesomelysecure.org/myCI/lookup_url?url=http%3A%2F%2Fwww.humbedooh.com%2F
Secondly, the lookup "doesn't work".
I have my sites set to cache elements for 2 hours (revalidate=2h), but neither the regular lookup nor the regex lookup seem to return any cached results for my site. I even tried looking up ".*" in the regex version, but to no avail. Am I doing something wrong (or missing a configuration) since this doesn't work, or is this a bug or a missing/incomplete feature?
