Does ASM Support HTTP/1.0?

Symptom

By default, Istio does not support HTTP/1.0.

Analysis

In Istio, Envoy forwards traffic and Pilot allocates rules. PILOT_HTTP10 of Pilot is set to 0 by default. This means HTTP/1.0 is not supported by default.

Solution

Set .values.pilot.env.PILOT_HTTP10 to 1 in the .iop file and configure PILOT_HTTP10 for pilot.
