You can need to use 

-glob
type matching so that you can match on and example.com. "*example1.com" essentially means - a host header that ends with "example1.com"

when HTTP_REQUEST { 
    log local0. "Host header is [HTTP::host]" 
    switch -glob [string tolower [HTTP::host]] { 
        "*example1.com" { 
            log local0. "matched example1.com" 
            pool number1 
        } 
        "*example2.com" { 
            log local0. "example2.com" 
            pool number2 
        } 
    } 
}
