PingGateway 2024.6

Configuration templates

This chapter contains template routes for common configurations. To use a template, set up PingGateway as described in the Quick install, and modify the template for your deployment. Before you use a route in production, review the points in Security.

Proxy and capture

If you installed and configured PingGateway with a router and default route as described in the Quick install, then you already proxy and capture the application requests coming in and the server responses going out.

This template route uses a DispatchHandler to change the scheme to HTTPS on login:

{
  "heap": [
    {
      "name": "ReverseProxyHandler",
      "type": "ReverseProxyHandler",
      "comment": "Testing only: blindly trust the server cert for HTTPS.",
      "config": {
        "tls": {
          "type": "ClientTlsOptions",
          "config": {
            "trustManager": {
              "type": "TrustAllManager"
            },
            "hostnameVerifier": "ALLOW_ALL"
          }
        }
      }
    }
  ],
  "handler": {
    "type": "DispatchHandler",
    "config": {
      "bindings": [
        {
          "condition": "${request.uri.path == '/login'}",
          "handler": "ReverseProxyHandler",
          "baseURI": "https://app.example.com:8444"
        },
        {
          "condition": "${request.uri.scheme == 'http'}",
          "handler": "ReverseProxyHandler",
          "baseURI": "http://app.example.com:8081"
        },
        {
          "handler": "ReverseProxyHandler",
          "baseURI": "https://app.example.com:8444"
        }
      ]
    }
  },
  "condition": "${find(request.uri.query, 'demo=capture')}"
}

To try this example with the sample application:

  1. Add the following route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/20-capture.json
    %appdata%\OpenIG\config\routes\20-capture.json

  2. Add the following route to PingGateway to serve the sample application .css and other static resources:

    • Linux

    • Windows

    $HOME/.openig/config/routes/00-static-resources.json
    %appdata%\OpenIG\config\routes\00-static-resources.json
    {
  "name" : "00-static-resources",
  "baseURI" : "http://app.example.com:8081",
  "condition": "${find(request.uri.path,'^/css') or matchesWithRegex(request.uri.path, '^/.*\\\\.ico$') or matchesWithRegex(request.uri.path, '^/.*\\\\.gif$')}",
  "handler": "ReverseProxyHandler"
}

  3. Go to http://ig.example.com:8080/login?demo=capture.

    The login page of the sample application is displayed.

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the baseURI settings to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.

Simple login form

This template route intercepts the login page request, replaces it with a login form, and logs the user into the target application with hard-coded username and password:

{
  "heap": [
    {
      "name": "ReverseProxyHandler",
      "type": "ReverseProxyHandler",
      "comment": "Testing only: blindly trust the server cert for HTTPS.",
      "config": {
        "tls": {
          "type": "ClientTlsOptions",
          "config": {
            "trustManager": {
              "type": "TrustAllManager"
            },
            "hostnameVerifier": "ALLOW_ALL"
          }
        }
      }
    }
  ],
  "handler": {
    "type": "Chain",
    "config": {
      "filters": [
        {
          "type": "PasswordReplayFilter",
          "config": {
            "loginPage": "${request.uri.path == '/login'}",
            "request": {
              "method": "POST",
              "uri": "https://app.example.com:8444/login",
              "form": {
                "username": [
                  "MY_USERNAME"
                ],
                "password": [
                  "MY_PASSWORD"
                ]
              }
            }
          }
        }
      ],
      "handler": "ReverseProxyHandler"
    }
  },
  "condition": "${find(request.uri.query, 'demo=simple')}"
}

To try this example with the sample application:

  1. Add the following route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/21-simple.json
    %appdata%\OpenIG\config\routes\21-simple.json

  2. Replace MY_USERNAME with demo, and MY_PASSWORD with Ch4ng31t.

  3. Add the following route to PingGateway to serve the sample application .css and other static resources:

    • Linux

    • Windows

    $HOME/.openig/config/routes/00-static-resources.json
    %appdata%\OpenIG\config\routes\00-static-resources.json
    {
  "name" : "00-static-resources",
  "baseURI" : "http://app.example.com:8081",
  "condition": "${find(request.uri.path,'^/css') or matchesWithRegex(request.uri.path, '^/.*\\\\.ico$') or matchesWithRegex(request.uri.path, '^/.*\\\\.gif$')}",
  "handler": "ReverseProxyHandler"
}

  4. Go to http://ig.example.com:8080/login?demo=simple.

    The sample application profile page for the demo user displays information about the request:

    Username 	demo

REQUEST INFORMATION
Method 	POST
URI 	/login
Cookies
…​

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the uri, form, and baseURI to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.

Like the previous route, this template route intercepts the login page request, replaces it with the login form, and logs the user into the target application with hard-coded username and password. This route also adds a CookieFilter to manage cookies.

The route uses a default CookieFilter to manage cookies. In this default configuration, cookies from the protected application are intercepted and stored in the PingGateway session. They are not sent to the browser. For information, see CookieFilter.

      "filters": [
        {
          "type": "PasswordReplayFilter",
          "config": {
            "loginPage": "${request.uri.path == '/login'}",
            "request": {
              "method": "POST",
              "uri": "https://app.example.com:8444/login",
              "form": {
                "username": [
                  "MY_USERNAME"
                ],
                "password": [
                  "MY_PASSWORD"
                ]
              }
            }
          }
        },
        {
          "type": "CookieFilter"
        }
      ],
      "handler": "ReverseProxyHandler"
    }
  },
  "condition": "${find(request.uri.query, 'demo=cookie')}"
}

To try this example with the sample application:

  1. Add the following route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/22-cookie.json
    %appdata%\OpenIG\config\routes\22-cookie.json

  2. Replace MY_USERNAME with kramer, and MY_PASSWORD with N3wman12.

  3. Add the following route to PingGateway to serve the sample application .css and other static resources:

    • Linux

    • Windows

    $HOME/.openig/config/routes/00-static-resources.json
    %appdata%\OpenIG\config\routes\00-static-resources.json
    {
  "name" : "00-static-resources",
  "baseURI" : "http://app.example.com:8081",
  "condition": "${find(request.uri.path,'^/css') or matchesWithRegex(request.uri.path, '^/.*\\\\.ico$') or matchesWithRegex(request.uri.path, '^/.*\\\\.gif$')}",
  "handler": "ReverseProxyHandler"
}

  4. Go to http://ig.example.com:8080/login?demo=cookie.

    The sample application page is displayed.

    Method 	  POST
URI 	  /login
Cookies
Headers  content-type: application/x-www-form-urlencoded
         content-length: 31
         host: app.example.com:8444
         connection: Keep-Alive
         user-agent: Apache-HttpAsyncClient/…​ (Java/…​)

  5. Refresh your connection to http://ig.example.com:8080/login?demo=cookie.

    Compared to the example in Login form with cookie from login page, this example displays additional information about the session cookie:

    Cookies  session-cookie=123…​

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the uri and form to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.

When a user without a valid session tries to access a protected application, this template route works with an application to return a login page.

The route uses a PasswordReplayFilter to find the login page by using a pattern that matches a mock AM Classic UI page.

Cookies sent by the user agent are retained in the CookieFilter, and not forwarded to the protected application. Similarly, set-cookies sent by the protected application are retained in the CookieFilter and not forwarded back to the user agent.

The route uses a default CookieFilter to manage cookies. In this default configuration, cookies from the protected application are intercepted and stored in the PingGateway session. They are not sent to the browser. For information, see CookieFilter.

}

To try this example with the sample application:

  1. Save the file as $HOME/.openig/config/routes/23-classic.json.

  2. Use the following curl command to check that it works:

    $ curl -D- http://ig.example.com:8080/login?demo=classic

HTTP/1.1 200 OK
Set-Cookie: IG_SESSIONID=24446BA29E866F840197C8E0EAD57A89; Path=/; HttpOnly
...

To use this as a default route with a real application:

  1. Change the uri and form to match the target application.

  2. Remove the route-level condition on the handler that specifies a demo query string parameter.

Login which requires a hidden value from the login page

This template route extracts a hidden value from the login page, and includes it the static login form that it then POSTs to the target application.

  "baseURI": "${appBaseUri}"
}

The parameters in the PasswordReplayFilter form, MY_USERNAME and MY_PASSWORD, can have string values or can use expressions.

To try this example with the sample application:

  1. Add the following route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/24-hidden.json
    %appdata%\OpenIG\config\routes\24-hidden.json

  2. Replace MY_USERNAME with scarter, and MY_PASSWORD with S9rain12.

  3. Add the following route to PingGateway to serve the sample application .css and other static resources:

    • Linux

    • Windows

    $HOME/.openig/config/routes/00-static-resources.json
    %appdata%\OpenIG\config\routes\00-static-resources.json
    {

  "handler": "ReverseProxyHandler"
}

  4. Go to http://ig.example.com:8080/login?demo=hidden.

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the loginPage, loginPageExtractions, uri, and form to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.

HTTP and HTTPS application

This template route proxies traffic to an application with both HTTP and HTTPS ports. The application uses HTTPS for authentication and HTTP for the general application features. Assuming that all login requests are made over HTTPS, you must add the login filters and handlers to the chain.

}

To try this example with the sample application:

  1. Add the following route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/25-https.json
    %appdata%\OpenIG\config\routes\25-https.json

  2. Add the following route to PingGateway to serve the sample application .css and other static resources:

    • Linux

    • Windows

    $HOME/.openig/config/routes/00-static-resources.json
    %appdata%\OpenIG\config\routes\00-static-resources.json

  "handler": "ReverseProxyHandler"
}

  3. Go to http://ig.example.com:8080/login?demo=https.

    The login page of the sample application is displayed.

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the loginPage, loginPageExtractions, uri, and form to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.

AM integration with headers

This template route logs the user into the target application by using headers such as those passed in from an AM policy agent. If the passed in header contains only a user name or subject and requires a lookup to an external data source, you must add an attribute filter to the chain to retrieve the credentials.

To try this example with the sample application:

  1. Add the route to PingGateway:

    • Linux

    • Windows

    $HOME/.openig/config/routes/26-headers.json
    %appdata%\OpenIG\config\routes\26-headers.json

  2. Use the curl command to simulate the headers being passed in from an AM policy agent, as in the following example:

    $ curl \
--header "username: kvaughan" \
--header "password: B5ibery12" \
http://ig.example.com:8080/login?demo=headers

...
<title id="welcome">Howdy, kvaughan</title>
...

To use this as a default route with a real application:

  1. Replace the test ReverseProxyHandler with one that is configured to trust the application’s public key server certificate. Otherwise, use a ReverseProxyHandler that references a truststore holding the certificate.

    Configure the ReverseProxyHandler to strictly verifiy hostnames for outgoing SSL connections.

    In production, do not use TrustAllManager for trustManager, or ALLOW_ALL for hostnameVerifier.

  2. Change the loginPage, uri, and form to match the target application.

  3. Remove the route-level condition on the handler that specifies a demo query string parameter.
