http-compression

my angular2 projects build pre-compressed gzip files for my web-app but my IIS only serves the normal ".js" files instead of the compressed ".gzip" files. My browser is willing to accept gzip. What is the correct setting for IIS to allow gzip responses? I already searched google/SO/SU but only found solutions for not "pre-compressed" content. A more neat and elegant solution: NOTICE: The file extension .gzip seems strange, in general, we name a gziped file as .gz , so in this example, we use .gz instead .gzip , if you insist on .gzip , just replace all the extensions in the following config

I'm not completely sure whether this belongs on SO, but I don't know where else to ask. While I was checking the loading speed of a web app of mine I noticed that apparently no HTTP response (no matter what type - html, css, js) is gzip/deflate compressed. That is, no response header like "Content-Encoding: gzip" is present in any request and the browser reports that the resource is not compressed. tested and confirmed in multiple browsers (IE10, FF 17, Chrome 23, Opera 12.10, Safari 5.x) tested and confirmed on two machines running Windows 8 Pro double checked with Fiddler - the response is

I have the following web.config: <urlCompression doStaticCompression="true" /> <httpCompression> <dynamicTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </dynamicTypes> <staticTypes> <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/javascript" enabled="true" /> <add mimeType="*/*" enabled="false" /> </staticTypes> </httpCompression> May plan does not allow Dynamic compression The problem is,

mod_deflate or mod_gzip , which should be used? I read mod_gzip on better explained but want to know extra about mod_deflate . You should read " Compressing Web Content with mod_gzip and mod_deflate " by Stephen Pierzchala. From a pragmatic point of view, I suggest mod_deflate because it is easy to configure, well documented , and actively maintained. Also, a precompiled version of mod_deflate is more than likely available for your server. Apache may even come with mod_deflate , as is the case with the Windows installer and apache2.2-bin Debian package. Eduardo While looking for mod_deflate, I

I currently have both static and dynamic compression configured. The static compression is working, however the dynamic compression, when checked through YSlow and Fiddler, is not working. In my applicationHost.config, I have the following settings: <urlCompression doStaticCompression="true" doDynamicCompression="true" dynamicCompressionBeforeCache="true" /> <httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" maxDiskSpaceUsage="100" minFileSizeForComp="256"> <scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" dynamicCompressionLevel="1" />

I use following .htaccess to set gzip compression: AddOutputFilterByType DEFLATE text/html image/png image/jpeg text/css text/javascript Please check this url: http://www.coinex.com/cn/silver_panda/proof/china_1984_27_gram_silver_panda_coin/ the gzip compression works for html, css, js and jpg, but not working for png (really amazing..) Rob Trickey PNG is already a compressed data format. Compressing it with GZIP is not likely to decrease the size, and can in fact make it larger. I'm surprised you're seeing benefits when GZIP-ing JPGs, as they are also compressed. See here for Google's tips on

I have heard a lot that one should use gZip for their webpages for faster access and downloads, and that it also saves the bandwidth. So what is this gZip compression and how does it make the downloads faster ? Does it compress the HTML and images or just the HTML. If I am to start using gZip in my webapps what considerations do I need to make ? Are there any server or browser restrictions for it, or does it support a particular encoding only. GZip is a form of data compression -- ie it takes a chunk of data and makes it smaller. The original data can be restored by un-zipping the compressed

What InputStream type should be used to handle URLConnection streams that have HTTP Content-Encoding set to deflate ? For a Content-Encoding of gzip or zip I use a GZIPInputStream, no problem. For a Content-Encoding of "deflate" I have tried using InflaterInputStream and DeflaterInputStream but I get java.util.zip.ZipException: unknown compression method at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:147) My understanding is that "deflate" encoding refers to Zlib compression, and according to the docs this should be handled by InflaterInputStream.
