Receive String problem

Hi,   I'm trying to create a regular monitor that would monitor a website with:   Send String: GET / HTTP/1.0   Receive String: Welcome Page   When I do telnet "IP of the Node"...

The app is sending a 400 error indicating a bad request. I'd guess it doesn't like the empty host header. It might also be an issue with the carriage return / line feeds on the monitor. You could try configuring the actual host header value the server expects in the send string and experiment with one or two \r\n's at the end:

 

 

GET / HTTP/1.1\r\nConnection: Close\r\nHost: \r\n

 

 

GET / HTTP/1.1\r\nConnection: Close\r\nHost: \r\n\r\n

 

 

GET / HTTP/1.1\r\nConnection: Close\r\nHost: actualhost.example.com\r\n

 

 

GET / HTTP/1.1\r\nConnection: Close\r\nHost: actualhost.example.com\r\n\r\n

 

 

Once you get a 200 OK response, the pool member(s) will be marked up and the VIP will process requests.
