Byte serving is the process of sending only a portion of an HTTP/1.1 message from a server to a client. Clients which request byte-serving might do so in cases in which a large file has been only partially delivered and a limited portion of the file is needed in a particular range. Byte Serving is therefore a method of bandwidth optimization.[1] In the HTTP/1.0 standard, clients were only able to request an entire document. By allowing byte-serving, clients may choose to request any portion of the resource. One advantage of this capability is when a large media file is being requested, and that media file is properly formatted, the client may be able to request just the portions of the file known to be of interest. This has been reported to work for some PDF files and clients in which a client may request a certain page, rather than the entire file. Other names for byte serving:
- Section 14.35.2 of RFC 2616 says the client makes Range Retrieval Requests when it makes a partial content request
- Clients make range requests [2][3]
- Byte Range Serving[4]
- Page on demand[5]
The use of the Chunked Transfer-Encoding is not byte-serving, but is instead method in which only a portion (or chunk) of data is sent by the server in an HTTP/1.1 session.[6] It is often used when a server knows that it will take a long time to complete a client's request, and so it sends only small chunks of data as the data is dynamically created. Byte serving and chunking are compatible with or without the presence of the other.
