load balance using http methods

We have 1 read/write node and two Read-only nodes, so we want all the Get http requests to be distributed equally in them and all other requests like POST, Patch, Delete to be forwarded to read/write node 

 

Example :-

Node1 : R/W " it will receives Get , Post,Patch,Delete "

Node2 : Read-only "it will receives Get Requests only "

Node3 : Read-only "it will receives Get Requests only "

 

Thank you in advance

    Hi Ahmed,

    Can you try this iRule?

    when HTTP_REQUEST {
	if { [HTTP::method] ne "GET" } {
		node node1ip port
	}
	# GET requests are forwarded to the default pool. No need to use else statement.
}
