Given your cURL string, the monitor send string should look something like this:

GET /gatewaymonitoringtool/default.aspx?servername HTTP/1.1\r\nHost: monitoringserver\r\n\r\n

This will send just the request line and Host header. You may want to test with the cURL command to see if the application actually needs these other headers (rare but possible):

curl -v http://monitoringserver/gatewaymonitoringtool/default.aspx?servername -H "Accept:" -H "User-Agent:"

Also, because your monitor request isn't encrypted, you should be able to tcpdump on that interface and see what the actual traffic looks like between the monitor and the server:

tcpdump -lnni 0.0 -Xs0 port 80 [and any additional filters]
