Re: [Bigdata-developers] How to use RDR with Curl

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

If you use POST with a URL of the resource to be loaded (see the NSS wiki
page) then the URL must be accessible by bigdata.  If you are using the
form of POST that sends the data in the http request body (which is the
case here), then it only needs to be visible to the client making the
request.

Thanks,
Bryan
