Going further on investigation, I've some little problems: 1- strange caracters appearing on the conductor screen (A like symbol on capture of virtuoso conductor screen) 2- with isparql, it seems that some stylesheet does not apply (can be compared between the two ispaql captures attached)
Any idea of complementary parameterization on the proxying in order to avoid such issue? Note that my remote server is on debian. Best regards.
