Use check_http instead. It's much better suited to this task. For  
example, I use --

define command {
     command_name                   check_caching
     command_line                   $USER1$/check_http -H www.ena.com - 
I $HOSTADDRESS$ --onredirect follow -p 8080 -wt 20 -ct 30 -to 35 -u http://www.ena.com 
  -R \/html
}

This translates to 'ask the proxy at $HOSTADDRESS$ on port 8080 to get  
the index page at http://www.ena.com, follow any redirects received  
and look for the string "/html" in the page.'
