It is probably adding white-space chars such as new line. Regex are basically 
line oriented and new-line may cause problems. In any case instead of using 
OK[\r\n] I would recommend something like this to allow for optional 
white-space chars both in front and behind the OK but nothing else. Heck, this 
must work:

and content == '^[ \r\n\t]*OK[ \r\n\t]*$'

Unless you have content-type set to text/plain that is not at all unlikely 
since text/html viewed in the browser hide white-space chars such as new-line.
