Matching URL content against regular expression

[Gonzalez, Fernando (FOM)]

Hi, I am trying to get monit to check a URL and verify the content with 
a regular expression. For that I use this configuration:

CHECK HOST fergonco WITH ADDRESS fergonco.es
         if failed
                 port 80 protocol http
                 and request /tmp/a with content = "ab"
         then alert

If I remove the "with content" part I get the report is ok, but when I 
put it says "connection failed" and in the log I get this:

[CEST Jun 10 21:31:00] error    : 'fergonco' failed protocol test [HTTP] 
at INET[fergonco.es:80/tmp/a] via TCP -- HTTP error: Regular expression 
doesn't match: No match

I am trying to access a file that contains just "abccc", I know what a 
regular expression is and I have tried many combinations. Still, I must 
be doing some silly mistake. I have searched the mailing list and 
existing documentation with no luck. Any help would be appreciated.

Regards.
