Re: URL content checking [Vote]

[Jan-Henrik Haukeland]

The new URL statement and content checking is finally added to monit. 
I'm swamped down in work so this has unfortunately taken more time than 
I hoped. Anyway, the statement can be used as follows:

   check host FOO with address www.foo.bar
       if failed URL http://www.foo.bar:8080/?query#ref
          and content == "my regular.*expression$"
          and with timeout 15 seconds
       then ..

The original plan to introduce a new "check URL" statement is dropped 
for now. I think the above should suffice? The new code is in the CVS 
and you can follow the instructions here 
http://savannah.nongnu.org/cvs/?group=monit to checkout monit using 
anonymous access. See also documentation in monit.pod.

I hope you will find this new code useful. Please let me know if this 
works for you.

Ps. When testing the content, monit will download up to max 1Mb from 
the http server or what's specified in the content-length header. This 
should be more than enough. Probably to much really.
