If the acl keyword is a "fetch", the dedicated parsing function "sample_parse_expr()" is used. Otherwise, the acl parsing function "parse_acl_expr()" is extended to understand the syntax of a series of converters placed after the "fetch" keyword. Before this patch, each acl uses a "struct sample_fetch" and executes it with the "<fetch>->process()" function. Now, the dedicated function "sample_process()" is called. These syntax are now avalaible: acl bad req.hdr(host),lower -m str www http-request redirect prefix /go-away if bad acl bad hdr_beg(host),lower www http-request redirect prefix /go-away if bad
