It's an OR. The purpose is not to be used like that, but rather have an ACL which indicates a match that can come from multiple places. Here are a few examples :
acl static hdr_beg(host) static. acl static hdr_beg(host) images. acl static hdr_beg(host) video.
acl localhost src 127.0.0.1
acl localhost hdr(host) -i localhost acl localhost hdr_ip(host) 127.0.0.1
acl forbidden_req hdr_cnt(content-length) gt 1 acl forbidden_req hdr_cnt(host) ne 1 acl forbidden_req hdr_cnt(max-forwards) ne 1 acl forbidden_req url_reg ^[^:/]*://
You see ? it's really for having one single variable be true in such circumstances. This becomes more obvious when using real ACL names which indicate the purpose of the ACL.
