Hello.
With the new parameters, I did some tests with the following queries:
- Failed - logs at the end below:
select * where { service <http://dbpedia.org/sparql> { dbpedia:Uruguay ?p ?o } }
- Works fine:
select * where { service <http://lod.openlinksw.com/sparql> { dbpedia:Uruguay ?p ?o } } ;
- Failed - logs at the end:
define get:soft "soft" select * from <http://dbpedia.org> where { dbpedia:Uruguay ?p ?o }
- Works fine:
define get:soft "soft" SELECT * FROM <http://lod.openlinksw.com/c/9BW76GGL> WHERE { ?s ?p ?o } ;
As I said in a previous message, this situation makes me think about how is making the connection in case of 303 . What’s the meaning of n_redirects= 0 in http_client_ext ?
Thanks.
FDO.
