- readBuffer
- HTTP client request data.
- offset
- Index of the first byte to decode.

You can call this method many times to decode chunks of client data as they received from an HTTP request.
Use the Execute property to decide when the request data is completely received and decoded.
This method will update the Leadtools.Jpip.HttpServer.HttpClientRequest properties and fill the Headers and Args while processing.
