Does Facebook Login validate redirect URIs before TLS certificate verification?

I need to determine the order in which Facebook Login validates OAuth redirect URIs and TLS server certificates during the authorization-code flow. The App Dashboard requires exact redirect-URI matches, while certificate validation is delegated to the operating-system or SDK trust store. Facebook documentation does not state whether an unregistered redirect

Ktor client TLS versus java.net.InetAddress DNS: independent hostname verification and async resolution

The Ktor client relies on the JVM’s SSLContext for TLS and hostname verification, while its DNS lookup is performed synchronously through java.net.InetAddress. Ktor does not expose a flag to disable certificate validation or to supply an alternate DNS resolver, and engine‑specific settings such as sslContext or dnsResolver must be provided via the underlying

In a Nuxt hybrid application, using useFetch or useAsyncData creates different environments depending on the execution context. During server-side rendering (SSR), the request is initiated by the Node.js runtime, which relies on the host's DNS configuration and CA trust store. Conversely, client-side fetching (CSR) utilizes the browser's native fetch API and

Discord.js gateway defaults to system DNS resolver with no override option

Discord.js establishes the WebSocket gateway through Node.js net and TLS modules, using the built-in dns module with the operating system's resolver to resolve gateway.discord.gg. No API is provided to specify alternative DNS servers or to supply custom TLS certificate authorities; certificate validation follows Node.js default root store behavior. When DNS

What determines Passport.js TLS certificate validation behavior when DNS resolution maps the authorization server hostname to an IP?

What determines Passport.js TLS certificate validation behavior when DNS resolution maps the authorization server hostname to an IP? Passport.js OAuth2 strategies rely on Node's https module for TLS certificate validation, and the default rejectUnauthorized option controls whether the module rejects certificates that do not match the presented hostname. When
