Question and assistance with monitor

For (1) , I've created a monitor that will do a GET to the uri like this

 

GET /hotelrates/getSampleExpressDeals.do?noOfDeals=1 \r\nHost: \r\nConnection: Close\r\n

 

 

Receive String is:

 

HTTP/1\.(0|1) (2|3)

 

 

Receive Disable String is

 

HTTP/1.\(0|1) (4|5)

 

 

This does not work. So the question is , does the port number has to do anything with it? can I use the URI or should i use the full URL? this URL is in each server, So i technically just need to change the host portion.have you run tcpdump on bigip to see what is going on? Aaron has written excellent monitor troubleshooting article as below.

to change host name for each server in pool, i understand you have to use external monitor.

when the pool member is marked down when an 500 error shows, what happens with it when the error goes away and the server is healthy? How can it be enable again?Note: Calling LB::down in an iRule triggers an immediate monitor probe regardless of the monitor interval settings.
