health monitor that worked in 10.0.1 failed with 10.2.1

Hi All,

 

 

With 10.0.1 code, a health check that checks for http GET requests and receive "200 OK" passed with no problems. When the code was upgraded from 10.0.1 to 10.2.1, all servers that had this health check were marked down causing an unexpected outage.

 

 

 

I run the same health check on the F5 CLI by doing telnet to port 80 on the server and sending the same GET request and I get a "200 OK" response.

 

 

 

I am not sure what the problem is. I increased the timeout but the problem is not due to the timeout.

    Kalpesh,

     

     

    Did you try move the space after colon instead of before for Connection eg GET /exploit-mag-csg/ HTTP/1.1\r\nHost:bfc.saint-gobain.com\r\nConnection: Close\r\n\r\n
