(DataFlex) Send XMLHttpRequest using PUT, GET, DELETE, or any HTTP Request Method

The PostXml method is the easiest way to send an XMLHttpRequest using the POST HTTP verb (which is by far the most common). To use a different HTTP request method (such as PUT, GET, DELETE, etc.), the SynchronousRequest method should be called. It provides more flexibility in constructing the exact HTTP request desired.

Note: This example requires Chilkat v11.0.0 or greater.
