I have an ICAP server backend with servers that each listen on different ports, can anyone offer some advice on how to configure health checks for it? I am currently using basic but that really doesn't help if the service is not responding.
Here is my haproxy config for the backend: backend HTPL_CONT_FILTER_tcp_ipvANY mode tcp balance roundrobin timeout connect 50000 timeout server 50000 retries 3 server HTPL-WEB-01_10.1.4.153 10.1.4.153:1344 check inter 5000 weight 200 maxconn 200 fastinter 1000 fall 5 server HTPL-WEB-02_10.1.4.154 10.1.4.154:1344 check inter 5000 weight 200 maxconn 200 fastinter 1000 fall 5 server HTPL-WEB-02_10.1.4.155_01 10.1.4.155:8102 check inter 5000 weight 200 maxconn 200 fastinter 1000 fall 5 server HTPL-WEB-02_10.1.4.155_02 10.1.4.155:8202 check inter 5000 weight 200 maxconn 200 fastinter 1000 fall 5 If I use curl and get the headers from a healthy response here is what is returned: curl -v http://10.1.4.155:8202/ * Hostname was NOT found in DNS cache * Trying 10.1.4.105... * Connected to 10.1.4.105 (10.1.4.105) port 8181 (#0) > GET http://10.1.4.155:8202/ HTTP/1.1 > User-Agent: curl/7.35.0 > Host: 10.1.4.155:8202 > Accept: */* > Proxy-Connection: Keep-Alive > < HTTP/1.1 200 OK * Server squid/3.4.10 is not blacklisted < Server: squid/3.4.10 < Mime-Version: 1.0 < Date: Sun, 18 Oct 2015 23:49:22 GMT < X-Transformed-From: HTTP/0.9 < X-Cache: MISS from HTPL-PROXY-02 < X-Cache-Lookup: MISS from HTPL-PROXY-02:3128 < Transfer-Encoding: chunked < Via: 1.1 HTPL-PROXY-02 (squid/3.4.10) < ICAP/1.0 400 Protocol Error ISTAG: "5BDEEEA9-12E4-2" Service: Diladele Web Safety 4.2.0.CBF4 Connection: close Encapsulated: resp-body=0 ICAP Protocol error: icap_header - unknown ICAP method found * Connection #0 to host 10.1.4.105 left intact TIA...
