The only way I can get this test to work is by prefixing the filename with a
'%' in order to make it a regex.
By trial and error, and not as a regex, I have tried escaping the colon and
comma characters. I have tried including the whole of the filename in single
quotes and double quotes, and then repeated that on literally just the filename
part.
All of these failed.

Oddly I repeated the DS settings on a different client server (same xymon
server), and noticed that the RRD filename was different.
In the hosts.cfg file, if I use 'httpstatus;http://x1...' then the filename
produced is 'tcp.http.x1...'.
But if I use 'httpstatus;https://x2...' then the filename becomes
'tcp.http.https:,,x2...'. The '://' part of the URL is now included in the
filename (and commafied(!)).

Anyway, it's back to the code I guess.
