That is correct, BIG-IP will load balance the first request to the Front End servers, but after that the clients will communicate directly to them.

Hi mikeshimkus,

 

Why is the first request directed to the FrontEnd VS and the subsequent client communication directly with with front end servers? Why aren't the subsequent requests directed towards the F5 FrontEnd Virtual Server and based on persistence records forwarded to the Actual front end server? Shouldn't all communication take place via F5?

 

If this it the normal working behavior can you please direct me to exact resource of documents which specifies this. The point is if F5 is also acting for the first request only and subsequent connections are directly to the FrontEnd Servers it's more or less similar to DNS load balancing.
