Description
Event to post-process the data before you send it to the remote protocol.
OnBeforeSendData allows you to process the raw data before you send it to the remote protocol.
Because OnBeforeSendData acts as an exit point for the raw data that you send, you can use OnBeforeSendData to compress or scramble the data.
The event handler of this event accepts the following parameters:
Sender: the instance of the client that sends the data.ADataBuffer: the raw data the client sends (array of bytes).
The event handler of OnBeforeSendData needs to return the processed data.
