Subject: [MINOR] acl: provide the argument length for fetch functions
X-Git-Tag: v1.3.12~16
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bb76891d0ffa5f81a86e426f3e2680132a4ff971;p=thirdparty%2Fhaproxy.git

[MINOR] acl: provide the argument length for fetch functions

Some fetch() functions will require an argument (eg: header).
It's wise to provide the argument size to optimize string
comparisons.
