I'm trying to configure parent servers for hierarchical caching in a forward proxy mode, but I am showing strange effects.
I have 3 servers:
- The ATS 3.0 server (172.16.1.144)
- The parents (172.16.1.195, 172.16.1.196)
My installation is clean and I've changed only a few parameters.
CONFIG proxy.config.url_remap.remap_required INT 0
CONFIG proxy.config.http.parent_proxy_routing_enable INT 1
dest_domain=. parent="172.16.1.195:8080; 172.16.1.196:8080" round_robin=strict
If I request http://www.apache.org from my web browser, I see, using "tcpdump port 8080 -nn" in the ATS 3.0 machine connections to "220.127.116.11.8080" (www.apache.org) but nothing to the parent servers.
Connectivity between the ATS and the parents are confirmed using telnet to the 8080 port, and is responding to HTTP requests.
If I disable the parent config, ATS 3.0 works well.
