http\_config: optional HTTPConfiguration { allow\_insecure, expected\_body, expected\_codes, 5 more } Parameters specific to an HTTP or HTTPS health check.

allow\_insecure: optional boolean Do not validate the certificate when the health check uses HTTPS. Link to this property expected\_body: optional string A case-insensitive sub-string to look for in the response body. If this string is not found, the origin will be marked as unhealthy. Link to this property expected\_codes: optional array of string The expected HTTP response codes (e.g. “200”) or code ranges (e.g. “2xx” for all codes starting with 2) of the health check. Link to this property follow\_redirects: optional boolean Follow redirects if the origin returns a 3xx status code. Link to this property header: optional map\[array of string] The HTTP request headers to send in the health check. It is recommended you set a Host header by default. The User-Agent header cannot be overridden. Link to this property

method: optional "GET"or "HEAD" The HTTP method to use for the health check.

One of the following: "GET" Link to this property "HEAD" Link to this property
