HTTP Header Compression via Body Relocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional compression techniques for HTTP messages are inadequate in reducing the size of messages with substantial information in the header, as they only compress the body while leaving the header intact, leading to inefficient resource management in devices with limited bandwidth and processing power.
Innovation Solution
An electronic device is configured to reformatted HTTP messages by moving header information into the body, allowing for compression of both the body and the relocated header information, using identifiers to facilitate decompression and reconstruction at the recipient end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional compression techniques are used to compress only the body of HTTP messages, then the body size is reduced, but the header size remains unchanged resulting in insufficient overall message size reduction
Solution Approach 1:
The patent merges the header information with the body content by placing header data into the body section of the HTTP message. This allows the compression algorithm to process the entire message as a single unit, achieving superior overall compression ratios compared to compressing header and body separately.
Solution Approach 2:
The patent segments the HTTP message into identifiable components (header information and body content) while allowing them to be physically combined for compression. The header information is extracted, compressed together with the body, and then reassembled with proper formatting to maintain protocol compliance.
2Quantity of substance
If header information is moved into the body for compression, then message size is reduced, but message structure complexity increases
Solution Approach 1:
The patent introduces an intermediary processing layer that handles the reformatting, compression, and reconstruction of HTTP messages. This intermediary component manages the complexity of moving header information into the body while maintaining the overall structure and compliance with HTTP protocols.
Solution Approach 2:
The patent changes the structural parameters of the HTTP message by relocating header information into the body section. This parameter change enables compression of the entire message while maintaining the ability to reconstruct the original structure through decompression and reformatting operations.
3Loss of energy
If compression is applied to reduce message size, then bandwidth consumption is reduced, but processing overhead increases
Solution Approach 1:
The patent applies compression operations preliminarily to the entire HTTP message before transmission. By pre-compressing the message with header information integrated into the body, the system reduces bandwidth consumption during transmission while the processing overhead is confined to the compression and decompression phases.

AI summary
Techniques for HTTP header compression are described herein. In an implementation, an electronic device may be configured to enable compression/decompression of HTTP messages, including compression/decompression of information in the headers of the messages. A HTTP message is generated that contains at least a header and a body. The HTTP message is reformatted to place at least some of the header information into the body. Then, the body of the reformatted message having the header information is compressed to form a compressed HTTP message. Decompression may be applied by a recipient of the compressed HTTP message to reconstruct the original HTTP message.
