Web Caches (proxy server)

• user sets browser: Web accesses via web cache

• client sends all http requests to web cache

  • if object at web cache, web cache immediately returns object in http response
  • else requests object from origin server, then returns http response to client

Goal: satisfy client request without involving origin server
