#ERROR XZ COMPRESSION NOT AVAILABLE PATCH#

xz - LZMA2-based content compression, supported by a non-official Firefox patch and fully implemented in mget since.

LZ77-based compression optionally using a Huffman encoding.

xpress - Microsoft compression protocol used by Windows 8 and later for Windows Store application updates.

rsync - delta encoding in HTTP, implemented by a pair of rproxy proxies.

peerdist – Microsoft Peer Content Caching and Retrieval.

lzma – compression based on (raw) LZMA is available in Opera 20, and in elinks via a compile-time option.

bzip2 – compression based on the free bzip2 format, supported by lighttpd.

In addition to these, a number of unofficial or non-standardized tokens are used in the wild by either servers or clients:

zstd – Zstandard compression, defined in RFC 8478.

pack200-gzip – Network Transfer Format for Java Archives.

This is the default value for content coding. This method is the most broadly supported as of March 2011. Uses the deflate algorithm for compression, but the data format and the checksum algorithm differ from the 'deflate' content-encoding.

gzip – GNU zip format (described in RFC 1952).

deflate – compression based on the deflate algorithm (described in RFC 1951), a combination of the LZ77 algorithm and Huffman coding, wrapped inside the zlib data format (RFC 1950).

compress – UNIX 'compress' program method (historic deprecated in most applications and replaced by gzip or deflate).

br – Brotli, a compression algorithm specifically designed for HTTP content encoding, defined in RFC 7932 and implemented in all modern major browsers.

The official list of tokens available to servers and client is maintained by IANA, and it includes: The web server is by no means obligated to use any compression method – this depends on the internal settings of the web server and also may depend on the internal architecture of the website in question. HTTP / 1.1 200 OK Date : mon, 26 June 2016 22:38:34 GMT Server : Apache/1.3.3.7 (Unix) (Red-Hat/Linux) Last-Modified : Wed, 23:11:55 GMT Accept-Ranges : bytes Content-Length : 438 Connection : close Content-Type : text/html charset=UTF-8 Content-Encoding : gzip

For Content-Encoding, the list is in a field called Accept-Encoding for Transfer-Encoding, the field is called TE. The web client advertises which compression schemes it supports by including a list of tokens in the HTTP request. The negotiation is done in two steps, described in RFC 2616:ġ. Compression using Content-Encoding is more widely supported than Transfer-Encoding, and some browsers do not advertise support for Transfer-Encoding compression to avoid triggering bugs in servers. At a higher level, a Content-Encoding header field may indicate that a resource being transferred, cached, or otherwise referenced is compressed. At a lower level, a Transfer-Encoding header field may indicate the payload of an HTTP message is compressed. There are two different ways compression can be done in HTTP.

The most common compression schemes include gzip and Brotli a full list of available schemes is maintained by the IANA.

HTTP data is compressed before it is sent from the server: compliant browsers will announce what methods are supported to the server before downloading the correct format browsers that do not support compliant compression method will download uncompressed data. HTTP compression is a capability that can be built into web servers and web clients to improve transfer speed and bandwidth utilization.
