Does WAF support connecting wildcard domain names?

Yes. You can connect a wildcard domain name in the WAF console.

Note：

• If a wildcard domain name, such as *.test.com, is already connected to Tencent Cloud, then any of its sub-domain names cannot be connected to another account.
• If the wildcard domain name *.test.com is already connected to your account, then wildcard domain names in formats such as *.a.test.com cannot be connected to this account.
• If you add both a wildcard and a precise domain name (e.g. *.test.com and a.test.com), WAF first uses the protection policies configured for the precise domain name.
