3.9.2 How can I tell when a site is HTTP/1.1? When you are visiting at site whose server is HTTP/1.1, you will see the number "1.1" in the box on the lower left hand corner of the VoyagerNG window. Of course, this only applies to VNG2.92 and above. The current public release of Voyager, 2.95, can take advantage of HTTP/1.1.
