API parameter reference

Create different overrides by including different action parameters in the action_parameters field:

​​ Host header override parameters

The full syntax of the action_parameters field for overriding the HTTP Host header is the following:

"action_parameters": {
  "host_header": "<HOST_HEADER_VALUE>"
}

​​ Resolve override and destination port override parameters

The full syntax of the action_parameters field for overriding both the hostname and the destination port of incoming requests is the following:

"action_parameters": {
  "origin": {
    "host": "<HOSTNAME>",
    "port": <PORT>
  }
}

If you are only overriding the hostname or the port, omit the port or host parameter, respectively.

​​ SNI override parameters

The full syntax of the action_parameters field for overriding the SNI value of incoming requests is the following:

"action_parameters": {
  "sni": {
    "value": "<SNI_VALUE>"
  }
}

​​ Configuring several overrides in the same rule

The same Origin Rule can have different types of overrides. For example, a single Origin Rule can perform an HTTP Host header override and a destination port override. The syntax of such a rule would be the following:

"action_parameters": {
  "host_header": "<HOST_HEADER_VALUE>",
  "origin": {
    "host": "<HOSTNAME>",
    "port": <PORT>
  }
}
