    • init

      public void init(javax.servlet.ServletConfig sc) throws javax.servlet.ServletException
      Reads the following variables from the servlet config:
      • AuthMgr - the authentication manager to use to authenticate the request
      • GetClientCert - whether to request client auth for this request
      • authority - the authority (ca, ra, drm) to return to the client
      • dynamicVariables - a string of the form: serverdate=serverdate(),subsystemname=subsystemname(), http=http(),authmgrs=authmgrs(),clacrlurl=clacrlurl()
      The dynamicVariables string is parsed by splitting on commas. When services, the HTTP request provides a piece of javascript code as follows.

      Each sub expression "lhs=rhs()" forms a javascript statement of the form lhs=xxx; Where lhs is xxx is the result of 'evaluating' the rhs. The possible values for the rhs() function are:

      • serverdate() - the timestamp of the server (used to ensure that the client clock is set correctly)
      • subsystemname()
      • http() - "true" or "false" - is this an http connection (as opposed to https)
      • authmgrs() - a comma separated list of authentication managers
      • clacrlurl() - the URL to get the CRL from, in the case of a Clone CA. This is defined in the CMS configuration parameter 'cloning.cloneMasterCrlUrl'
