Abstract
Methods are provided for controlling access to information in a distributed computing system. A request for the information is received and is accompanied by encrypted session state data. Based on the encrypted session state data, it is determined whether to pass the request on to a source of the information. In a memory buffer, old data is replaced by overwriting with a unique identifier. After the memory buffer has received new data and a procedure has been executed for copying the contents of the memory buffer to a destination, it is determined whether the unique identifier may be found at the destination.
