We should use `(*regexp.Regexp).MatchString` instead of
`(*regexp.Regexp).Match([]byte(...))` when matching string to avoid
unnecessary `[]byte` conversions and reduce allocations.
Example benchmark:
var allowedOrigin = regexp.MustCompile(".*.example.com")
func BenchmarkMatch(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := allowedOrigin.Match([]byte("www.example.com")); !match {
b.Fail()
}
}
}
func BenchmarkMatchString(b *testing.B) {
for i := 0; i < b.N; i++ {
if match := allowedOrigin.MatchString("wwww.example.com"); !match {
b.Fail()
}
}
}
