Apache load balancing after F5

[hk17]

Hello All ,

Im working on a scenario where we have a F5 for SSL unload , which is internet facing (which is controlled by different person/team ) .
In the F5 configuration the applications vm and paths are mapped with port numbers(typically 4 Tomcat application servers) .

Present configuration :
Request ------>F5 -------> app1 ----- app2 .........app3

Need is we are increasing the number of application servers and cluster them ( 1 application 2 nodes ) . And the application nodes are scaled frequently as pre the requirement .
For which the changes are not allowed in the F5 .
Is there any way to do this ... or any link which provides me info .

F5 ------ apache 2.4 ---- app1-node1 ....... app1-node2
|
|----apache 2.4 -----app2 -node1........app2-node2 .


I'am asking this question as im new to web world.


Thanks ,
