Re: How to check for a path in a url and restart runit if fails

[Callum Macdonald]

I think rather than exec you want just restart, that will have the
effect of restarting the service. So something like:

if failed host 127.0.0.1 port 80 protocol http
  request /pixel
  hostheader 'my.webserver.name'
  then restart

I believe this is far more elegant than repeating the restart commands
in each exec statement, but I might have missed something, it's late in
this timezone! :-)

Cheers - Callum.
