FIELD: information technology.
SUBSTANCE: present invention involves the use of the HTTP/1.1 "chunked" mode to deliver updates of the file delivery table (FDT) of a session in a push-like mode. In order to allow for push delivery of the contents of a FLUTE session, each FDT instance is encoded as one part of a multipart multipurpose internet mail extensions (MIME) message and is sent as a separate chunk. The receiver can interpret each of the separate chunks to extract the FDT instance from the chunks. The content type of each part of the message is set to text/xml or another MIME type in order to indicate that the content is an FDT instance. After parsing the FDT instance and updating the FDT, the receiver is able to identify which files of the session are of interest and can perform a HTTP GET request to retrieve a specific file.
EFFECT: ensuring integrity of the obtained content without duplication thereof while reducing consumption of resources.
