Hi there,
RDFConnectionRemote is built around a HttpClient from Apache HttpClient.
HttpClient objects are built with a fixed configuration.
Like wise the configuration for RDFConnectionRemote is set when built
and remains fixed for the lifetime of the connection.
You can
(1) build a RDFConnectionRemote for different settings (they are not
expensive to build).
(2) use the lower level code such as QueryExecutionFactory.sparqlService
and UpdateExecutionFactory.createRemote
Or use the implement code like QueryEngineHTTP.setClient but that is
digging into the implementation.
