Configuring HTTP health check parameters
For HTTP hosts, you also can customize the health check by changing the URL method and the string requested by the ServerIron ADX, as well as the HTTP status codes the ServerIron ADX accepts as valid responses. By default, the ServerIron ADX performs the HTTP health check as follows:
•The ServerIron ADX sends a HEAD request for the default URL string, “HEAD /”.
•If the server responds with the status code 401 or a code in the range
You can change the request method from HEAD to GET. In addition, you can change the URL string the ServerIron ADX requests from the server and the status codes that the ServerIron ADX accepts as valid responses for passing the health check.
The commands in the following example change the method from HEAD to GET and to add 404 as a valid status code response to the health check.
ServerIronADX(config)# gslb dns zone brocade.com
Syntax:
GET or HEAD is an optional parameter that specifies the request type. By default, HTTP keepalive uses HEAD to retrieve the URL page. You can override the default and configure the ServerIron ADX to use GET to retrieve the URL page.
The slash ( / ) is an optional parameter. If you do not set the GET or HEAD parameter, and the slash is not in the configured URL page, then ServerIron ADX automatically inserts a slash before retrieving the URL page.
