Need syntax eyes on badtest entry

I'm trying to give a little resiliency to reporting on an Outlook Web Access server that intermittently returns bad https results without visibly disrupting user services. "badhttps" doesn't seem to be working for me. I have:

xx.xxx.xx.xxx webmail.example.com # noconn noping https://webmail.vita.example.com/Exchweb/bin/auth/owalogon.asp badhttps:2:3:5
COMMENT:"external prod Shared E-mail Web Interface"

IP and hostname are of course obfuscated. It's on two lines, as indicated by the "\". But it still appears to go red on a single https failure. Can anyone out there point out my error?
