snort rules

Vern,
    I am trying to test how the signature engine works with snort rules.What I do is loading http-request.bro and snort.bro, adding "redef signature_files += snort-default.sig;" in the latter and visiting the host by "http://……/etc/passwd".But there is still no rule matching.
  I find that in the function of Match in class RuleMatcher, "m->state->Match((const u_char*) data, data_len, bol, eol)" still returns false.Would you please tell what's wrong?

Tad
