Wildcard subdomains are a fantastic solution when your domain handles numerous subdomains, like those generated by users.
To configure a wildcard subdomain, you would set the source as: *.example.com.
Key Points to Note:#
• Plan Availability: Wildcard subdomains are accessible from our Pro plan onwards.
• Usage Calculation: Each wildcard source is equivalent to using 3 source hostnames due to the extensive SSL certificate management involved.
• Fair-Use Policy: If you have a large number of subdomains (over 100), it falls under our fair-use policy to ensure smooth operation for all users.
• SSL Certificates for non-enterprise plan: We issue an SSL certificate for each subdomain. These certificates are automatically installed upon the first request, ensuring secure connections for all your subdomains.
• SSL Certificates for Enterprise plan: We issue a wildcard SSL certificate for your domain. This certificate will applied to all your subdomains, ensuring secure connections for all your subdomains.
Sending each subdomain to its own destination#
A wildcard source is usually combined with destination variables, so one rule can send every subdomain to a different place. For example, {host.sub} inserts the subdomain that was requested:
textSource: *.example.com
Destination: https://www.example.com/team/{host.sub}
alice.example.com → https://www.example.com/team/alice
bob.example.com → https://www.example.com/team/bobYou can also keep the subdomain on a new domain with https://{host.sub}.new-brand.com and turn on Path forwarding. See Destination URL Variables for the full list of variables and more examples.
Wildcard subdomains offer flexibility and efficiency, making them ideal for domains with dynamic subdomains. With RedirHub, you can manage these seamlessly while maintaining high security standards.
