The HTTP Service will use the return value of the createRequest callback as the request body (if supported by the HTTP method). If this is an array of non-null HTTPRequestPart objects, then a multi-part request will be formed. Otherwise the object is converted to a String and used.
The default value is BASIC.
This only caches status codes 2xx with a content length and size of less than 50k that are not immediately written to file. The URL and the user name are used as cache keys. The total size of cacheable content and the number of cached items is limited and automatically managed by the system.
Cache control information sent by the remote server is ignored.
Caching HTTP responses should be done very carefully. It is important to ensure that the response really depends only on the URL and doesn't contain any remote state information or time information which is independent of the URL. It is also important to verify that the application sends exactly the same URL multiple times.
The default value is UTF-8.
If this is not set and mTLS is used then the private key will be chosen from the key store based on the host name. If this is set to a reference named "__NONE__" then no private key will be used even if one is requested by the remote server.
The default behavior is to not write a file.
