HTTP/HTTPS form configuration:

ConfigMap	Description
Task name	Required. Enter a unique custom task name for this account.
Probe protocol	Mandatory. Select the DNS type.
Probe address	Mandatory. Provide the URL of the monitor object. It can be a domain name or an IP address for probing.
Request method	Both GET and POST methods are supported. Submission content: body content of HTTP POST request, sent in the format of JSONObject, such as {'test':'testValue'}
Advanced configuration	Disabled by default. Once enabled, the corresponding content will be displayed. Host: The HOST field in the request header, such as a domain name or an IP address. User-Agent: The User-Agent field in the HTTP request header. Cookie: The Cookie field in the HTTP request header. HTTP code matching: Specify particular HTTP codes, such as 501. Response content matching: Specify the content to match in order to confirm response accuracy. HTTP authentication username: Enter the corresponding username required for HTTP authentication. HTTP authentication password: Enter the corresponding password required for HTTP authentication.
Probe node	Required. Supports probe nodes for both IPv4 and IPv6 network types. Displays IPv4 probe nodes by default. When entering an IP address for probing, ensure the probe address type matches the network type. For a probe address in IPv4 format, choose the network type as IPv4. The same applies to IPv6.
Detection Period	Required. Specify the interval between two probes. Supports intervals of 1, 2, 5, 10, 15, or 30 minutes, or 1, 2, or 3 hours.
Timeout setting	Allows customization of the maximum duration for a single probe before marking it as failed. The timeout duration cannot exceed the probe interval. If left empty, the probe interval is used as the default timeout duration.

Probe address	Mandatory. Provide the URL of the monitor object. It can be a domain name or an IP address for probing.
Query method	Mandatory. Available options are "recursion" and "iteration," with "recursion" as the default. Recursion: The DNS query client only interacts with the LocalDNS, which queries root domain servers, top-level domain name servers, and authoritative domain servers. Iteration: The DNS query client queries hierarchical DNS servers independently until the final result is obtained.
DNS server	Not required. You can configure specific DNS servers to resolve the entered domain name. If not specified, the local DNS server of the probe node will be used by default.
DNS allow list	No required. During resolution of domain name (such as www.baidu.com), if the resolved IP address or CNAME is not in the DNS hijacking allow list, user access will fail or a non-Baidu target IP will be returned; if the resolved IP or CNAME is in the DNS allow list, it will be considered that no DNS hijacking has occurred. Specific rules and examples are as follows: Domain name: Matching rules. These rules support IP addresses, IP wildcards, and CNAMEs. Multiple rules can be entered, separated by vertical bars (\|). Example: www.baidu.com:112.80.248.76 \| 112.80.248.75 means that all IPs under the www.baidu.com domain, except 112.80.248.76 and 112.80.248.75, are considered hijacked. IP format (IP hijacking) Specify IP address; ipv4,eg. 192.168.1.1; ipv6, eg. 2400:A480:aa:400:a1:b2:c3:d4 wildcard Matching, eg.192.168.1.* indicates 192.168.1.1~254 all IP address Wildcard matching, eg. 2400:A480:aa:400:a1:b2:c3:* indicates 2400:A480:aa:400:a1:b2:C3:0~FFFF CNAME format (CNAME hijacking) Specify domain name address, e.g., www.baidu.com Wildcard matching, e.g. *baidu.com
Probe node	Required. Supports probe nodes for both IPv4 and IPv6 network types. Displays IPv4 probe nodes by default. When entering an IP address for probing, ensure the probe address type matches the network type. For a probe address in IPv4 format, choose the network type as IPv4. The same applies to IPv6.
Detection Period	Required. Specify the interval between two probes. Supports intervals of 1, 2, 5, 10, 15, or 30 minutes, or 1, 2, or 3 hours.
