This should be possible with the Binary Data object and the AJAX object. Using AJAX you can make two requests:
- Firstly use the AJAX object 'Set response binary' action to save the next request in a Binary Data
- Then use AJAX to request the GameRecorder.RecordingURL - this will load the recording in to the Binary Data
- Once that completes, you can do another AJAX request with 'Post binary to URL'. Choose the same Binary Data object to send, and then enter your server URL to post to.
In other words you first use AJAX to transfer the recording to a Binary Data object, and then you can use 'Post binary to URL' to send the contents of that Binary Data object to your server. You'll need to make sure the server can handle binary data coming in from the body of the POST request.
