1. perf: avoid allocations with (*regexp.Regexp).MatchString …

   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()
   		}
   	}
   }
