hit
tap

   1.  cache hit.

   2.  A request to a web server from a web
   browser or other client (e.g. a robot).

   The number of hits on a server may be important for
   determining advertising revenue.

   In the course of loading a single web page, a browser may
   hit a web server many times e.g. to retrieve the page itself
   and each image on the page.  In contrast, caching by
   browsers and web proxies reduces the number of hits on the
   server because some requests are satisfied from the cache.

   3.  To press and release a key on the keyboard.  Some
   prefer the less aggressive "tap".
