Symptoms
Traffic is dropped for "Non Compliant HTTP" with the reason:
"illegal header format detected: Malformed HTTP protocol name in request"
HTTP version 0.9 is used.
Cause
HTTP version 0.9 is not supported.
The gateway is expecting a HTTP version number in the GET request (ex. 'GET /index.html HTTP/1.0') but in HTTP Version 0.9, there is no version in the GET request (ex. 'GET /index.html').
