Description

Sends an HTTP request to the specified URL using the OPTIONS HTTP request method, waits for the server to send a response, and returns the HTTP response of the server.

If you want to receive the response data as your HTTP client downloads it from the target server, instead of waiting for your HTTP client to download the whole data, use the AResponseContent parameter to specify a stream to receive the downloaded data. Alternatively, you can wait for your HTTP client to download the whole response data, and obtain the response data as a stream from the ContentStream property of the response object that Options returns.

Regardless of whether you receive the data as it comes or wait for the whole data to be available, you can handle the OnReceiveData event to track the progress of the download of the response data.

Use AHeaders to include custom HTTP request headers in your HTTP request.

Options raises an ENetHTTPRequestException if the HTTP request reaches the maximum number of redirects.
