问题 We already know deflate encoding is a winner over gzip with respect to speed of encoding, decoding and compression size. So why do no large sites (that I can find) send it (when I use a browser that accepts it)? Yahoo claims deflate is "less effective". Why? I maintain HTTP server software that prefers deflate, so I'd like to know if there's some really good reason not to continue doing so. 回答1: There is some confusion about the naming between the specifications and the HTTP: DEFLATE as

I am trying to do a request that accepts a compressed response var request = (HttpWebRequest)HttpWebRequest.Create(requestUri); request.Headers.Add(HttpRequestHeader.AcceptEncoding, "gzip,deflate"); I wonder if when I add the second line I will have to handle the decompression manually. Jader Dias I found the answer. You can change the code to: var request = (HttpWebRequest)HttpWebRequest.Create(requestUri); request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate; And you will have automatic decompression. No need to change the rest of the code. For .NET Core

问题 I have a web service that is willing to output gzip/deflated data. I've verified that the service will respond with raw JSON or with gzip'd JSON using wget and curl. I want to consume this web service using the jQuery AJAX call. By default, the $.ajax call that jQuery provides does not add the "Accept-Encoding: gzip" HTTP request header that's necessary for the web server to respond with gzipped data. However, when I use jQuery's own methods to add the header, eg: $.ajax({url: 'http://foo.com

node.js - easy http requests with gzip/deflate compression

I'm trying to figure out how the best way to easily send HTTP/HTTPS requests and to handle gzip/deflate compressed responses along with cookies. The best I found was https://github.com/mikeal/request which handles everything except compression. Is there a module or method that will do everything I ask? If not, can I combine request and zlib in some manner? I tried to combine zlib and http.ServerRequest, and it failed miserably. Thanks! jcreignou Note: as of 2019, request has gzip decompression built in. You can still decompress requests manually using the below method. You can simply combine

UPDATE Feb 10 2012: zOompf has completed some very thorough research on this very topic here . It trumps any findings below. UPDATE Sept 11 2010: A testing platform has been created for this here HTTP 1.1 definitions of GZIP and DEFLATE (zlib) for some background information: " 'Gzip' is the gzip format, and 'deflate' is the zlib format . They should probably have called the second one 'zlib' instead to avoid confusion with the raw deflate compressed data format. While the HTTP 1.1 RFC 2616 correctly points to the zlib specification in RFC 1950 for the 'deflate' transfer encoding, there have

How to DEFLATE with a command line tool to extract a git object?

I'm looking for a command line wrapper for the DEFLATE algorithm. I have a file (git blob) that is compressed using DEFLATE, and I want to uncompress it. The gzip command does not seem to have an option to directly use the DEFLATE algorithm, rather than the gzip format. Ideally I'm looking for a standard Unix/Linux tool that can do this. edit: This is the output I get when trying to use gzip for my problem: $ cat .git/objects/c0/fb67ab3fda7909000da003f4b2ce50a53f43e7 | gunzip gzip: stdin: not in gzip format UPDATE: Mark Adler noted that git blobs are not raw DEFLATE streams, but zlib streams.
