domain-web-redirect

An AWS CDK construct that redirects all http/https requests for one domain to another.

DomainWebRedirect is an AWS CDK construct that redirects web requests for one or more source domains to a target domain. This could be used to redirect from the www domain (e.g. www.example.com) to the APEX / naked domain (e.g. example.com) or vice versa.

In addition to the source and target domain names you must also provide:

• the IHostedZone of each source domain
• one ICertificate that is valid for all source domains

Note that this uses 301 permanent redirects which browsers cache without an expiration date. This means that if you set this up and later modify the target domain you should also configure the old target domain to redirect to the new target domain.
