5.5.3. Request for Source Cluster IP Addresses

Publisher clients such as Replicator may need to know IP addresses of nodes in the CAStor source
cluster that Publisher listens to (in order to make SCSP requests to this cluster). The Publisher
Channel Server will support a request for a list of source cluster IP addresses and SCSP port
numbers:
GET /sourceclusteripports.bin HTTP/1.1
You will want to provide the publisher's IP address & the Publication Server Port as part of the
request. For example:
http://publisherIp:publicationServerPort/sourceclusteripports.bin
A normal response to this request is:
HTTP/1.1 200
Date: ...
Server: Content Router Publisher
Content-Type: text/plain
Content-Length: ...
Each line of the response body will be of the form "<source cluster IP address>:<SCSP port
number>". Over time, new source cluster nodes may come online and others may go offline, so
it may become necessary for a client to update its list of IP addresses. This could be done, for
instance, whenever a previously accessible source cluster node is no longer accessible, or at
regular time intervals.
