Guidance

All government websites must have www and non-www resolution.

About

Domain canonicalization allows access to the intended website address, whether users type www (www.example.gov) or not (example.gov). Improper canonicalization will fail to direct example.gov to the intended address, and users will receive an error.

Examples

Example of a government website with www and non-www resolution:

• https://digital.gov
• https://www.digital.gov
