Function HttpHead

HttpHead<T = unknown>(
url: string,
config?: Omit<HttpRequestConfig, "Url" | "Method" | "Body">,
): Promise<HttpResponse<T>>
Sends a HEAD request. Shorthand for HttpRequest with Method: 'HEAD'.

ResponseType is forced to none because a HEAD response has no body by definition, so Data is always null — use Status and Headers. Pair with ThrowOnError: false when probing a URL's reachability, so a 4xx is reported as a status rather than thrown.
Type Parameters
- T = unknown
  unused in practice; Data is always null.
Parameters
- url: string
  absolute URL, or a path when config.BaseURL is supplied.
- Optionalconfig: Omit<HttpRequestConfig, "Url" | "Method" | "Body">
  optional per-request settings.
Returns Promise<HttpResponse<T>>
the HttpResponse, with Data set to null.
Throws
on a non-2xx status (unless ThrowOnError is disabled), timeout, cancellation, or transport failure.
Example: Probing whether a link is alive
```
const response = await HttpHead(url, { ThrowOnError: false, Timeout: 10000 });
const reachable = response.Status >= 200 && response.Status < 400;
```
