Description

Starts an asynchronous HTTP request using the MERGE HTTP request method.

If your HTTP request must go through a proxy HTTP server that may not support the MERGE HTTP request method, use BeginMergeAlternative instead to disguise your MERGE request method as a PUT request method.

When you call BeginMerge, you must provide the data required to perform your HTTP request:

  • AURL is the target URL of your request.
  • ASource is a stream that contains the data to send.
  • AHeaders (optional) is a list of headers to include in the request.
  • AsyncCallback (optional) is a callback procedure to be called when a response is received or the request fails.
  • AsyncCallbackEvent (optional) is an event handler to be called when a response is received or the request fails.

For more information, see BeginExecute.
