Question

About asp.net core subdomain?

KaaN ErYuRt 0

Hello, I have a web application software with asp.net core 6. This application also has an API. For example, what I want to do is:

web application domain: www.example.com,

I want to access subdomains api.example.com and blog.example.com. For example, when I want to access the blog page through the web application, I want to provide a redirect such as blog.example.com/subject-detail-1 within the same application pool. The API running on the system works with www.example.com/api/.... I want to use it as api.example.com too. Are these possible with asp.net core? Could you please help me how to proceed?

As far as I can tell this is not a ASP.NET Core or C# question. If you want to create a subdomain, then contact your host and/or domain registrar for instructions.

Once you have the subdomains registered then you'll need certificates for each site or purchase a wild card certificate.

Next, host the sites. If you are using a hosting service then the hosting service should have instructions.

Lastly, the subdomains behave like separate sites. If you want to open the blog subdomain then just add a link.

Thank you for your response. Subdomains opened. My question is exactly this. You said "it behaves like separate sites". So as far as I understand, I cannot manage subdomains through a single application based on Asp.net Core.

Subdomains are managed/configured by the host not ASP.NET Core. Can you explain what "manage subdomains through a single application" means?

Which kind of server you are using to host and deploy the Asp.net core application? Windows (IIS) or Linux (Nginx, Apache)? You might need to set the server process manager.

you question is not clear. dns names just return an ipaddress. by default asp.net core does not check the host header (dns name used for request). In IIS the host header binding are at the site level.

in asp.net core you can write middleware to remap the url based on the host header. google for examples
