Make synchronous calls for 'send' actions. WARNING: this can cause deadlock if another BP is called by something called synchronously from here.
This setting is intended to ensure FIFO ordering when this router and the target Operations have PoolSize=1, and ancillary Operations might get
called asynchronously from within a Transform or Operation called from this router.
Note that if there are multiple 'send' targets, this setting means they will be called one after another in serial fashion, with the next being called after the previous call completes.
Also note that synchronous calls are not subject to the ResponseTimeout setting.
property ResponseFrom as %String (MAXLEN = 1000) [ Transient ];
Names the target(s) from which a response should be forwarded back to the caller, if the caller requested
a response. If this value is empty, no reply will be requested from any target. Otherwise, this value is a
comma-separated list of target config names. The response returned will be the first one that arrives back
from any target in the list. A value of '*' will match any target, so the first response received will be
the one returned.
If none of the listed targets gets called and the caller requested a response, an empty 'OK' response header
will be returned.
If the list of targets begins with a '+' character, the responses from all the targets called
will be returned as a list of message header IDs in the response header, or an empty 'OK' response header if no responses appear before the timeout expires.
If the list of targets begins with a '-' character, all error responses only from any of the targets called
will be returned as a list of message header IDs in the response header, or an empty 'OK' response header if no error responses appear before the timeout expires.
property ResponseTargetConfigNames as %String (MAXLEN = 1000);
Names a destination or destinations in addition to the caller to which responses will be forwarded.
If this value is empty, responses are only returned to the caller. If one or more target config names are listed
(separated by commas), each response from this router will be forwarded to each target config item listed.
This setting has effect only if ResponseFrom is not empty.
