newHttpClient
Creates a new HttpClient configured with HttpTimeout support.
The client uses whichever engine Ktor finds among the consumer's dependencies; this module declares none. On js and wasmJs, ktor-client-core falls back to its bundled Js engine. On the JVM and Kotlin/Native, add one (for example CIO, Darwin, Curl or WinHttp), or this call fails. The failure is Ktor's IllegalStateException wrapped in the platform's initialization error (ExceptionInInitializerError on the JVM), and only the first call carries it as the cause. The same applies to withHttpClient and httpClient when no client is passed.
