Does siege support HTTP/1.1 protocol?
Mostly. Support for protocol 1.1 has trickled in gradually. Starting with v2.03, an option was added to .siegerc to enable 1.1 protocol. Overtime, features of the protocol have gradually slipped into the program. The default protocol is now 1.1. To switch to 1.0 protocol make sure this directive is in your .siegerc file: protocol = HTTP/1.0.
