HAPROXY HDR

HAPROXY HDR

: 분배 알고리즘의 하나, HTTP Header 패킷의 특정 값을 참조하여 분배 결정

hdr(<name>) The HTTP header <name> will be looked up in each HTTP request.                   Just as with the equivalent ACL 'hdr()' function, the header                   name in parenthesis is not case sensitive. If the header is                   absent or if it does not contain any value, the roundrobin                   algorithm is applied instead.                   An optional 'use_domain_only' parameter is available, for                   reducing the hash algorithm to the main domain part with some                   specific headers such as 'Host'. For instance, in the Host                   value "haproxy.1wt.eu", only "1wt" will be considered.                   This algorithm is static by default, which means that                   changing a server's weight on the fly will have no effect,                   but this can be changed using "hash-type".
