HTTP MPLEX and HTTP MPLEX with extended syntax is described and examined in expanded detail in the doctoral Thesis Enhancing HTTP to Improve Page and Object Retrieval Time With Congested Networks . ref http www.mattson.com.au robert index.php?Menu Research ref In an asymmetric network environment, a slow upstream link is naturally susceptible to congestion. HTTP exacerbates the problem by using many verbose requests to retrieve objects used by a web browser to compose a web page , thereby compounding the congestion. This congestion negatively affects Transmission Control Protocol TCP flow control that is reliant on the sender receiving positive cumulative acknowledgement to regulate segment transmission rates. HTTP MPLEX, is a header compression and response encoding scheme for HTTP. It is designed to compress traditional HTTP requests to conserve bandwidth multiplex multiple responses to a single sustained stream of data to speed response times eliminate head of line queue starvation with response multiplexing and improve application layer use of TCP by reducing the number of parallel TCP connections.

HTTP The HTTP response List of HTTP status codes status code 301 Moved Permanently is used for permanent redirection. This status code should be used with the HTTP location location header.

Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URI s .

The POST request method is used when the client needs to send data to the server as part of the request, such as when uploading a file or submitting a completed form. In contrast to the GET HTTP GET request method where only a URL and headers are sent to the server, POST requests also include a message body. This allows for arbitrary length data of any type to be sent to the server. Headers in the POST request may indicate the message body s Internet media type to the server.

Texture compression is a specialized form of image compression designed for storing texture map s in 3D computer graphics rendering systems. Unlike conventional image compression algorithms, texture compression algorithms are optimized for random access . How it works In their seminal paper on http graphics.stanford.edu projects flashg papers texture compression texture compression ref Citation author Andrew Beers coauthors Maneesh Agrawala, Navin Chaddha title Rendering from Compressed Textures journal Computer Graphics, Proc. SIGGRAPH year 1996 pages 373 378 ref , Beers, Agrawala and Chaddha list four features that tend to differentiate texture compression from other image compression techniques. These features are Decoding Speed It is highly desirable to be able to render directly from the compressed texture data and so, in order not to impact rendering performance, decompression must ... , any texture compression scheme must allow fast random access to decompressed texture data. This tends to rule out image compression schemes such as JPEG or Run length encoding . Compression Rate and Visual Quality In a rendering system, lossy compression can be more tolerable than for other use cases. Encoding Speed Texture compression is more tolerant of asymmetric encoding decoding rates as the encoding ..., most texture compression algorithms involve some form of fixed rate lossy compression lossy vector ... maps, texture compression may also be used to encode other kinds of rendering map, including bump map s and normal mapping surface normal map s. Texture compression may also be used together with other ... of practical texture compression systems are S3 Texture Compression , PVRTC and Ericsson Texture Compression .

File Compression test.jpg right thumb 250px Compression test on a universal testing machine Physical compression is the result of the subjection of a material to compressive stress , which results in reduction of volume as compared to an uncompressed but otherwise identical state. The opposite of compression in a solid is tension physics tension . In any medium transmitting waves, the opposite of compression is rarefaction . In simple terms, compression is a pushing force. Explanation Compression has many implications in materials science , physics and structural engineering , for compression yields noticeable amounts of Stress physics stress and tension mechanics tension . By inducing compression, mechanical properties such as compressive strength or modulus of elasticity , can be measured. Scientist s and engineer s may utilize compression machines to measure the resistance of materials and structures to compression. Compression machines range from very small table top systems to ones with over 53 MN capacity. ref Citation last NIST title Large Scale Structure Testing Facility url http www.nist.gov bfrl facilities instruments large scale struct testing fac.cfm accessdate 04 05 2010 postscript . ref In engines Internal combustion engines In internal combustion engine s it is a necessary condition of economy to compress the explosive mixture before it is ignited in the Otto cycle , for instance, the second stroke of the piston effects the compression of the charge which has been drawn into the cylinder by the first forward stroke.
