HTTP grep

Loads page specified by URL option. If fails (not HTTP code 200 OK ) - sets ERR status. If page content do not have text specified in musthave option - sets ERR status. If page content has text specified in mustnothave option - sets ERR status.

Otherwise sets OK status.

Option options (usually empty) can have values ‘ssl_noverify’ and ‘addr=a.b.c.d’. If ssl_noverify specified, check will be successful even if SSL certificate verification fails. If addr is specified, request will be to IPv4 address a.b.c.d.
