Ron Barber created TS-2530:
------------------------------
Summary: False positive detected for Multi-Hop cycle when using
private IP
Key: TS-2530
URL: https://issues.apache.org/jira/browse/TS-2530
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Ron Barber
With hosts A and B running ATS where both hosts have private IPs (10.0.0.1 &
10.0.0.2) AND have a local loopback which have a public IP 27.1.1.1 we are
getting HTTP/1.1 400 Multi-Hop Cycle Detected when host A forwards a request to
host B.
ATS searches the incoming Via header for its own ip address
(Machine::instance()->ip_hex_string) to determine if the request has been
forwarded back to itself.
Cause: ATS is selecting the public IP address of the server to insert in the
Via header (even if it's not on a routable interface).
