How to avoid, that URL.equals needs access to the internet in Java?

Question

The equals() method of the URL class in the Java class library makes a DNS request to get the IP for the hostname, to check the two IP's for equality. This happens even for URLs that are created from the same String. Is there a way to avoid this internet access?

Answer 1

Use java.net.URI instead of URL.

Answer 2

If you just want to compare the url strings, try

url1.toString().equals(url2.toString())

Answer 3

Don't use URL.equals. As the documentation says,

Note: The defined behavior for equals is known to be inconsistent with virtual hosting in HTTP.
