HTTP Health Check Parameters (/cfg/slb/advhc/health <health check ID> http>/http) 
Command Syntax and Usage
method [get|head|post]
 
Sets the HTTP method.
Default: get
host [host|inherit|none]
 
Sets the host header.
Values:
*host — Specifies the host header to be used in the health check request (up to 128 characters), and Alteon sends an HTTP 1.1 request.
*inherit — Takes the value from the virtual service hostname (hname) and virtual server domain name (dname) values of the group to which this health check is bound.
*none — No host header is configured, and Alteon sends an HTTP 1.0 request..
path [path|inherit|none]
 
Specifies the request path. If empty, the request is sent to the Web service root (“/”). When the inherit option is selected, the path is taken from the content value of the group to which this health check is bound.
Maximum characters: 256
Caution: Alteon automatically adds a forward slash ( / ) to the path string. If you start the path string with slash, Alteon sends health check with two slashes ( // ), which causes the health check to fail.
header <512 chars headers separated by enter|none>
 
Sets the request header.
body <1024 chars body|none>
 
Sets the request body.
auth [none|basic|ntlm2|ntlmssp]
 
Specifies whether the monitored server requires authentication.
Default: none
Note: The Windows 2003 operating system supports the ntlm2 health check. Later versions of the Windows operating system support only the ntlmssp health check.
response [incl|excl|none]
 
Specifies the expected response. The return string can only be configured if the return string type is not set to none.
Values:
*incl — The health check is successful when the defined string appears in the response.
*excl — The health check is successful when the defined string does not appear in the response.
*none — The health check does not search for a defined string.
Default: none
Note: The return string is case-sensitive.
overload [incl|none][none]: incl
 
Specifies whether to move a real server to the overload state when an HTTP(S) health check detects a specified string in the real server response.
In the overload state, the real server maintains existing connections. New connections are not allocated to such a server, unless the /cfg/slb/group/maxconex command is enabled for the server group and the new connection belongs to an existing persistent session (with pbind set to clientip, sslid, or cookie).
Values:
*none — Alteon does not implement the overload state.
*incl — The real server is moved to the overload state when the string defined in the string command is detected in the real server response.
Default: none
proxy
 
Enables or disables the proxy request.
http2 [enabled|disabled]
 
When enabled, Alteon monitors servers via HTTP/2 (required only when using the Alteon native HTTP/2 load balancing proxy capability. Contact Radware Technical Support for details).
Default: disabled
cur
 
Displays the current configuration.
