execute more than 1 sparql queries

Hi,

Client send a Sparql query to my service, which then the code pass the query to QueryFactory.create(), and then pass the returned query object to QueryExecutionFactory.create()

Now client wants to send 2 queries (instead of making 2 calls to my service), can QueryFactory.create take more than 1 Sparql queries in this case?


Thanks,

Z

One query at a time for various reasons.

The HTTP keep-alive should take care of the efficiency by leaving the
connection open and reusing the TCP stream.  If both ends play that game
correctly.
