Create the application in Access Gateway
During this task we will create the web socket header application, which will host WebSocket policy.
Create the application in Access Gateway
- Sign in to the Access Gateway Admin UI console.
-
Click the Applications tab.
-
Click +Add.
-
Select the Header Based option from the application menu, then click Create.
-
Enter the following in the Essentials section:
Field Value Label A name for the application. For example header-websocket application. Public Domain A fully qualified host name. In this example www.mywebsocketapp.com. Protected Web Resource The URL of the protected resources. This is backend.websocket.com in the example. Group Enter the group containing the users who should have access to the application. Description Optional. An appropriate description for your application.
Configure load balancing
Only use Access Gateway as the load balancer. See Load balancing.
- Expand the Protected Web Resource tab.
- Enable Load Balancing By Access Gateway.
A table of hostnames and weights representing the target load balancing instances appears. This table is initially empty. Click edit
to modify an entry in the table, or click delete
to delete an entry. - Choose either HTTP or HTTPS as the URL scheme. Each protected web resource that you add inherits this scheme.
- Optional. Enable and specify Host Header value.
- Complete the following steps to add a host, repeat as required:
- Click Add protected web resource.
- Enter a fully qualified hostname:port combination (for example, https://backendserver1.atko.com:7001).
- Enter a weight from 1 to 100. Enter 0 to specify that a host is disabled.
Weights represent the percentage of requests that will be routed to this host.
For example, two hosts of weights 2:1 would result in requests being routed ~66% to the host weighted 2 and ~33% to the host weighted 1.
- Click Okay.
-
Optional. Configure health checks, which use GET operations to confirm that back-end resources are functional.
New requests aren't routed to resources that have been labeled unhealthy by the health checks.
- Enable Load Balancer Health Check.
- Click Edit to modify health check settings.
- Modify settings as required.
Field Value Default
Path URI to resource used in health check. / Method HTTP method used. Always GET Status code HTTP status code used to determine health. 200 Interval Interval between health checks in seconds. 10 Request timeout Health check request timeout in seconds. 1 Healthy threshold Number of successful requests before a host is considered healthy. 3 Unhealthy threshold Number of failed requests before a host is considered unhealthy. 3 - Click Save to save changes or click Cancel to exit without saving.
