Content check, exact match

Hi.

Found out that I could use the digest check for this.

Subject: [Xymon] Content check, exact match

Hi.

I want to setup a content check that alerts if a web page does not contain exactly "OK" and nothing more. It should alert if it shows "OK_MASTEROFFLINE" for example. I tried setting the content to ^OK$, but that did not work.
Has anyone done this? Are there other characters I can use to specify start and end of the string?
