we have 3 external web urls which will come on our frontend f5 and redirect to internal web urls and use as a revers proxy

Hello, Kevin good afternoon.

I have prepared iRule below, could you please verify will work or not?

when HTTP_REQUEST { if {[string tolower [HTTP::host]] equals "site1ex.com"} { HTTP::redirect "http://site1in.com" }

   elseif {[string tolower [HTTP::host]] equals "site2ex.com"} {
    HTTP::redirect "http://site2in.com"
 } 

elseif { [string tolower [HTTP::host]] equals "site3ex.com"} {
HTTP::redirect "http://site3in.com"
}
 }

i am not sure but i hope it should also work as its if condition only.
