I'm running code that seems to hit the "AppendHeader" twice in the code. Response.Filter = New DeflateStream(Response.Filter, CompressionMode.Compress, True) Response.AppendHeader("Content-encoding", "deflate") ... Response.AppendHeader("Content-encoding", "deflate") I have tried using the following.... Response.Headers("Content-...
Hi, I used the YSlow Firefox add-on and it return the follow result: ----------------------------------------------------------------------------------------- Grade D on Compress components with gzip There are 3 plain text components that should be sent compressed * http://localhost:63808/WebSite/BemVindo/ * http://localhost:63808/Web...
I have plugged in the HttpCompress module to enable compression for my MVC web application. If I run my site through the development web server (Cassini) I have no troubles with the execution of compression. However when I deploy the site to IIS6 the compression is not executing. I have checked the source code of the compression librar...
I'm writing some scripts that are using the HTML 5 file API in FireFox 3.6. I got some deflated (compressed) files, and I need to inflate (uncompress) them. I found a few scripts while googling, but none of them have tests. So I'm a bit reluctant to use them. My question is: Browsers can inflate. Can I somehow piggyback on the inflatio...
Are there any open source DEFLATE encoder implementations for JavaScript? I need it to generate a binary format on the client-side that requires DEFLATE. ...
Hi this is my first Question :) I need a lib or way to compress a data in asp.net (vb) with the algorit deflate but the result inflate in javascript. I'm use a lib in javascript: deflate.js hxxp://www.codeproject.com/KB/scripting/Javascript_binaryenc.aspx?msg=2904739 First i'm deflate and convert to base64 the result but the result is...
I am porting a Python application to Android and, at some point, this application has to communicate with a Web Service, sending it compressed data. In order to do that it uses the next method: def stuff(self, data): "Convert into UTF-8 and compress." return zlib.compress(simplejson.dumps(data)) I am using the next method to ...
I'm trying to find a balance between performance and degree of compression when gzipping a Java webapp response. In looking at the Deflater class, I can set a level and a strategy. The levels are self explanatory - BEST_SPEED to BEST_COMPRESSION. I'm not sure regarding the strategies - DEFAULT_STRATEGY, FILTERED and HUFFMAN_ONLY I can...
I'm trying to use Zlib::Deflate.deflate on a massive file (4 gigs). There are obvious problems with doing that, the first of which being that I can't load the entire file into memory all at once. Zlib::GzipWriter would work, since it works with streams, but it's not zlib compression. Any ideas? ...
It seems to me, that mod_deflate in Apache 2.2 will always return: Content-Encoding: gzip and never: Content-Encoding: deflate It was explained to me, that although there may be a deflate algorithm, mod_deflate is named after a file-format, in which the algorithm could be any of: gzip, bzip. pkzip Of those three, mod_deflate provid...
I've read on a couple of blogs, notably here http://www.codinghorror.com/blog/2008/10/youre-reading-the-worlds-most-dangerous-programming-blog.html there are some advantages to using deflate zlib compression by comparisson to gzip one. I am trying to setup apache to only do deflate so I can run some tests. However, I am having difficult...
Hi, I'm starting new website and gonna include several JS libs and would like to know how .htaccess file template should look like with caching of media and JS files on? Whats better for compression, GZip or Deflate? Is it better/faster solution to serve those JS libs off the Google CDN perhaps then locally? I'm asking CDN question s...
Apache compress content only if receives "Accept-Encoding: gzip" in request header. If i set "Accept-Encoding: deflate" then Apache would not compress the response anymore. Does mod_deflate use gzip compression algorithm or deflate compression algorithm (aka zlib)? ...
I have a web application on a site that takes a while (~10 seconds) to complete a portion of the page near the bottom - it has been as optimized as it can be, and caching is not an option. We have compression enabled on the server via an .htaccess directive SetOutputFilter DEFLATE the problem is this causes the whole page to be held unt...
Hi, I have a web-service running on Windows Azure which returns JSON that I consume in my iPhone app. Unfortunately, Windows Azure doesn't seem to support the compression of dynamic responses yet (long story) so I decided to get around it by returning an uncompressed JSON package, which contains a compressed (using GZIP) string. e.g ...
I set up a server to use the Apache2 deflate recently. Some people started reporting long waiting times on certain pages. The page in particular is one that takes a long time to load, as it's gathering data from external sources. Usually it loads progressively, which is good for user feedback. The whole page can take 10-15 seconds to f...
Hi, I need to pre-compress some very large html/xml/json files (large data dumps) using either gzip or deflate. I never want to serve the files uncompressed. They are so large and repetitive that compression will probably work very very well, and while some older browsers cannot support decompression, my typical customers will not be usi...
Hi! I'd like to use gzip/deflate compression in my website on IIS7 basic shared hosting plan on GoDaddy server. I've applied many solutions that I found in web but none resolved my problem. My pages are not being compressed at all, the size keeps the same after processing them. I've tried to create a HttpHandler using DeflateStream bu...

I'm looking for a command line wrapper for the DEFLATE algorithm. I have a file (git blog) 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 thi...
