![]() The directive has a number of parameters specifying which kinds of proxied requests NGINX should compress. To configure compression of these responses, use the gzip_proxied directive. The fact that a request comes from a proxy server is determined by the presence of the Via header field in the request. Third party-provided bindings and ports include C#, Common Lisp, Crystal (programming language), Erlang, Go, Haskell, Lua, Java, Nim, Node.js, Perl, PHP, Python, R, Ruby, Rust, Smalltalk, and OpenCL.By default, NGINX does not compress responses to proxied requests (requests that come from the proxy server). Snappy distributions include C++ and C bindings. Unlike compression methods such as gzip and bzip2, there is no entropy encoding used to pack alphabet into the bit stream. More common compressors can compress this better. In this example, all common substrings with four or more characters were eliminated by the compression process. The first 2 bytes, ca02 are the length, as a little-endian varint (see Protocol Buffers for the varint specification). Wikipedia is a free, web-based, collaborative, multilingual encyclopedia project. ![]() The complete official description of the snappy format can be found in the google GitHub repository. The size of the dictionary was limited by the 1.0 Snappy compressor to 32,768 bytes, and updated to 65,536 in version 1.1. The length is the number of bytes to copy from the dictionary. The offset is the shift from the current position back to the already decompressed stream. The copy refers to the dictionary (just-decompressed data).
