The search form POSTed to /finger, an uncacheable URL with no search term in it, so every lookup re-ran the finger command even for repeated searches of the same user. Redirect any query/POST search to the canonical /finger/<username> path (and submit the form via GET, with a JS fast-path straight to that URL) so repeated lookups are served from the nginx response cache. A bare /finger with no user still lists local system users.
