  • Understanding user-agent strings via Microsoft Developer Network
  • In computing, a user agent is software (a software agent) that is acting on behalf of a user. For example, an email reader is a mail user agent, and in the SIP, the term user agent refers to both end points of a communications session. In HTTP, the User-Agent string is often used for content negotiation, where the origin server selects suitable content or operating parameters for the response. For example, the User-Agent string might be used by a web server to choose variants based on the known capabilities of a particular version of client software. (via Wikipedia)
