| The User-Agent header field contains information about the UAC originating
the request. This is for statistical purposes, the tracing of protocol
violations, and automated recognition of user agents for the sake of
tailoring Responses to avoid particular user agent limitations. However
revealing the specific software version of the user agent might allow the
user agent to become more vulnerable to attacks against software that is
known to contain security holes. Implementers SHOULD make the User-Agent
header field a configurable option.
For Example:
User-Agent: Softphone Beta1.5
