Hi! I am trying to capture an HTTP Request Header that gets added under certain circumstances in the backend. From the documentation I understand I can use a capture slot for that. This is what I tried in my stripped down config file:
... frontend fe_http bind 192.168.1.3:80 declare capture request len 32 default_backend be_api backend be_api balance leastconn option httplog # this would have ACLs in the real use case http-request add-header X-CD-Operation Upload http-request capture hdr(X-CD-Operation) id 0 server api01 api01:8081 However, when I start HAProxy (1.6.3 from the ppa:vbernat/haproxy1.6 repo), I get this error message: $ haproxy -d -f test.cfg [ALERT] 077/124109 (13586) : Proxy 'be_api': unable to find capture id '0' referenced by http-request capture rule. [ALERT] 077/124109 (13586) : Fatal errors found in configuration $ haproxy --version HA-Proxy version 1.6.3 2015/12/25 I assume I misunderstood something thoroughly, but I am at a loss. Cheers, Daniel
