    HTTP/1.1 requires a Host header and your send string does not include one. Try:

     

    send "GET /Enterprise/login.cmdx\r\nHost: host.example.com\r\n\r\n"

Monitors use HTTP 0.9 by default. Try this

 

GET /Enterprise/login.cmdx HTTP/1.1\r\nHost: example.com\r\nConnection: Close\r\n

 

See SOL2167 for send string details
