Description

Starts an asynchronous HTTP request using the PATCH HTTP request method masked as a PUT HTTP request method.

Specifically, the HTTP request that BeginPatchAlternative sends uses PUT as HTTP request method and includes the following HTTP request headers to indicate that your request is actually a patch request:

  • X-Method-Override: PATCH

Use BeginPatchAlternative if your HTTP request must go through a proxy HTTP server that may not support the PATCH HTTP request method, otherwise you can use BeginPatch instead.

When you call BeginPatchAlternative, 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.
