Support Extracting Hostnames From Multiple Certificates

[EmperorArthur]

Description

As a corporate developer, I load in multiple certificates when using Vite, and would like automatic URL hostname detection to work the same as it does for a single certificate.

Node explicitly allows multiple certificates and keys to be used, and this seems like an arbitrary, undocumented, Vite limitation.

Suggested solution

The resolveServerUrls function handles a single certificate. The logic could easily be expanded to handle multiple certificates.

httpsOptions?.cert && !Array.isArray(httpsOptions.cert)

Alternative

Support more than one "host" in the server config section.

Adding custom host URLs involves writing a plugin with the following:

export function MyPlugin(): VitePlugin {
  return {
    name: "MultipleUrlPlugin",
    async configureServer(this: MinimalPluginContextWithoutEnvironment, server: ViteDevServer): Promise<void> {
      httpsServer.on('listening', () => {
        server.resolvedUrls = customResolveServerUrls(...)
      })
    }
  }
}

Additional context

Node v22 has some problems with multiple certificates, and can use PFX files as well as cert/key pairs. Bugs/Feature requests relating to those are outside the scope of this.
