irule redirect

I would recommend using 2 different iRules. One for VS:80 and another for VS:443. This way you can prevent unwanted iRule processing in VS:80 that is not required.

iRule in VS:80

when HTTP_REQUEST {
HTTP::redirect "https://[HTTP::host][HTTP::uri]" 
}
}

iRule in VS:443

when HTTP_REQUEST {
set my_uri [string tolower [HTTP::uri]]
set my_host [string tolower [HTTP::host]]
if {[string tolower [HTTP::uri]] contains "/flowers"} {pool Flower_POOL}
elseif {[HTTP::uri] contains "/net1"} {pool NET_ALL_POOL}
elseif {[HTTP::uri] contains "/net3"} {pool NET_ALL_POOL }
elseif {[HTTP::uri] contains "/fruit"} {pool Flower_POOL}
elseif {[HTTP::uri] contains "/candy"} {pool Flower_POOL}
elseif {[HTTP::uri] contains "/APACHE7/" } {node 10.1.1.8 7}
elseif {[HTTP::uri] contains "/APACHE8/" } {node 10.1.1.8 80}
elseif {[HTTP::uri] contains "/APACHE9/" } {node 10.1.1.9 80}
elseif {[string tolower [HTTP::uri]] contains "/testweb/"} {pool TESTWEB_POOL}
else {pool SERVER_TEST_POOL}
}
