Java
C++

public void Process( 
   byte[] readBuffer,
   int offset,
   int length
)

'Declaration
 
Public Sub Process( _
   ByVal readBuffer() As Byte, _
   ByVal offset As Integer, _
   ByVal length As Integer _
)

'Usage
 
Dim instance As HttpClientRequest
Dim readBuffer() As Byte
Dim offset As Integer
Dim length As Integer
 
instance.Process(readBuffer, offset, length)

public:
void Process( 
   array<byte>^ readBuffer,
   int offset,
   int length
)

Parameters

readBuffer: HTTP client request data.
offset: Index of the first byte to decode.
length: The number of bytes 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 HttpClientRequest properties and fill the Headers and Args while processing.
