table 1 each of the parameters table 1 may be specified explicitly or by a string of literal characters pre or post fixed or both by the asterisk wildcard character the asterisk matches zero or more literals a uri matching rule consists of one or more interesting uris against which all requested uris are compared the actions associated with a uri matching rule are triggered if any of the interesting uris associated with it match the requested uri the invention permits telecommunications carriers and network operators the requisite flexibility and fluidity over the actions which occur when subscriber 39 s trigger matches though the uri matching engine all actions performed when uris are matched by the uri matching engine are defined by mechanisms labeled as u2018 action plug ins u2019 action plug ins are implemented as java classes or suitable equivalent per the state of the art conforming to the action plug in api and use information from the http request and response messages to perform required system functions an action plug in when triggered by a uri matching rule is provided with the details of the http message in question including all http headers said plug ins are also provided with parameters defined in the uri matching rule the plug in uses the http data to perform tasks which for instance may innovatively include call outs to remote systems action plug ins are triggered by uri matching rules when the invention discovers a request for an interesting uri each uri matching rule may be associated with several actions plug ins and they may be prioritized to execute in any order action plug in code is invoked at two.
