Further information
1. This function corresponds to the
httppost function of the
mmhttp module and works in a similar way.
2. The outgoing HTTP request will be automatically augmented with the appropriate credentials for this type of
dmpresource.
3. In event of an unexpected failure, the request will be retried the number of times specified by
dmp_max_retries if it returned a HTTP status code listed in
dmp_retry_error_codes.
4. If this function returns an unexpected HTTP status code, you should check the
status attribute of the
dmpresource to see whether this was returned from the HTTP webservice or was the result of an error obtaining credentials.
