NAME
    Perlbal::Plugin::ExpandSSL - Add a custom header according to the SSL of
    a service

VERSION
    Version 0.02

SYNOPSIS
    This plugin adds a custom header according to information it reads off
    the SSL certificate of a service you've configured.

    Since Perlbal speaks plain HTTP to backends (while being able to serve
    HTTPS to clients), the backend does not know whether the client tried to
    reach HTTPS or HTTP.

    This plugin reads the certificate Perlbal is configured to serve the
    user, and adds an according header to the backend so it knows.

    In your Perlbal configuration:

        LOAD ExpandSSL

        CREATE SERVICE https_balancer
          SET role          = reverse_proxy
          SET pool          = machines
          SET plugins       = ExpandSSL
          SET enable_ssl    = on
          SET ssl_key_file  = /etc/perlbal/certs/mydomain.key
          SET ssl_cert_file = /etc/perlbal/certs/mydomain.crt
          SET plugins       = ExpandSSL

SUBROUTINES/METHODS
  register
    Register a service hook to run a callback to build a registry of headers
    for each request.

  build_registry
    The is the function being called to create the registry. It starts by
    decoding the cert file and then building the registry using a hardcoded
    headers hash.

    Don't like it? Patches are welcome! :)

  serialize_pem
    Takes a PEM-formatted certification file (the type you give Perlbal or
    your regular webserver to serve to the client) and returns only the Base
    64 portion of it.

    Basicaly it removed the header and footer in a clean manner.

  expand_ssl
    Sets the special headers from the registry. This uses the
    *start_proxy_request* hook.

  unregister
    Clears up the registry.

  load
    Nothing.

  unload
    Nothing.
