when open the page url from browser, the page got with gzip encoding but the can't viewe the page content - it seems the page was not decoded
returned page in browser have gzip encoding:
result in browser:
You can try to add the following code to you web.config file to enable compression for both static and dynamic content.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<system.webServer>
<urlCompression doStaticCompression="true" doDynamicCompression="true" />
<httpCompression>
<dynamicTypes>
<clear />
<add enabled="true" mimeType="text/*"/>
<add enabled="true" mimeType="message/*"/>
<add enabled="true" mimeType="application/x-javascript"/>
<add enabled="true" mimeType="application/javascript"/>
<add enabled="true" mimeType="application/json"/>
<add enabled="false" mimeType="*/*"/>
<add enabled="true" mimeType="application/atom+xml"/>
<add enabled="true" mimeType="application/atom+xml;charset=utf-8"/>
</dynamicTypes>
<staticTypes>
<clear />
<add enabled="true" mimeType="text/*"/>
<add enabled="true" mimeType="message/*"/>
<add enabled="true" mimeType="application/javascript"/>
<add enabled="true" mimeType="application/atom+xml"/>
<add enabled="true" mimeType="application/xaml+xml"/>
<add enabled="true" mimeType="application/json"/>
<add enabled="false" mimeType="*/*"/>

I have followed this document and have enabled both Dynamic and Static compression for my website.
But when I test the website here, the compression is not enabled.
I have verified the HttpCompression:
<system.webServer>
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
<staticTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/atom+xml" enabled="true" />
<add mimeType="application/xaml+xml" enabled="true" />
<add mimeType="image/svg+xml" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="*/*" enabled="false" />
</dynamicTypes>
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
</httpCompression>
</system.webServer>
I have also checked the following IIS Settings:
I see from your posted headers that the site is behind cloudfront (ie the via and x-cache headers).
Thus you may need to investigate having cloudfront provide compressed data: https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/ServingCompressedFiles.html
I'm not particularly familiar with cloudfront, but since its adding the via header its acting as a proxy..
..you have noCompressionForProxies = True in your IIS settings screenshot.
This has some info on changing that setting https://community.spiceworks.com/topic/1989103-help-with-enabling-nocompressionforproxies-in-applicationhost-config-in-iis
As a 1st test you could try to hit your site by-passing cloudfront to directly test the IIS setup.
Problems with activating Gzip on IIS 8 on a windows server 2012 (standard)
So i activated the compressions in the windows features
I checked both checkboxes in IIS - compression (dynamic and static)
But still no Gzip available. However, on my localhost machine (just a windows 10) this works.
What i do see, is that the gzip temp directory (C:\inetpub\temp\IIS Temporary Compressed Files) is getting filled up when i browse my site via the server localhost. BUT strangely enough i'm not seeing anything Gzip-ped in chrome.
The only headers (in chrome) are: HTTP/1.1 304 Not Modified Accept-Ranges: bytes ETag: "0a354779de8d11:0" Server: Microsoft-IIS/8.0 X-Powered-By: ASP.NET Date: Thu, 28 Jul 2016 13:41:04 GMT
(Even yslow is saying no gzip is activated)
When i remove the gzip temp folder, and browse to the site trough the 'official' website url, then nothing is even generated.
Does anyone has any idea what is going on here?
I added this in my web.config
<httpCompression>
<staticTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</dynamicTypes>
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" dynamicCompressionLevel="4" />
</httpCompression>
See this other topic, where i activated more log information, Gzip not working, server 2012, IIS 8
All i get is:

Can you try adding this to your web.config file ?? I suggest so because it worked for me on IIS windows shared hosting. Its similar to your code with a few changes...
<system.webServer>
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll"/>
<dynamicTypes>
<add mimeType="text/*" enabled="true"/>
<add mimeType="message/*" enabled="true"/>
<add mimeType="application/javascript" enabled="true"/>
<add mimeType="application/javascript; charset=utf-8" enabled="true"/>
<add mimeType="application/x-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="application/javascript; charset=utf-8" enabled="true"/>
<add mimeType="application/x-javascript" enabled="true"/>
<add mimeType="*/*" enabled="false"/>
</staticTypes>
</httpCompression>
<urlCompression doStaticCompression="true" doDynamicCompression="true"/>
</system.webServer>
I'm not sure if you need to add
<add mimeType="image/jpeg" enabled="true" />
Isn't jpeg a compressed format ? You could add it none the less if you wish to.
[OPTIONAL]: I read this at MaxCdn.
Origin servers should include Vary: Accept-Encoding, and here’s how:
<system.webServer>
<httpProtocol>
<customHeaders>
<remove name="Vary"></remove>
<add name="Vary" value="Accept-Encoding"></add>
</customHeaders>
</httpProtocol>
</system.webServer>
You can add this bit to your web.config file as well, deploy and check it in the request headers through your browser's developer tools itself.
Does anyone know why the following web.conig changes will NOT work:
<httpCompression>
<staticTypes>
<add mimeType="application/javascript" enabled="true"/>
</staticTypes>
<dynamicTypes>
<add mimeType="application/javascript" enabled="true"/>
</dynamicTypes>
</httpCompression>
After i added javascript files were still not being compressed (gzip). I thrased around for a couple days because i really didn't know what the problem was at first but now i do. If i change the applicationhost.config directly though it does work:
<httpCompression directory="%TEMP%\iisexpress\IIS Temporary Compressed Files">
<scheme name="gzip" dll="%IIS_BIN%\gzip.dll" />
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/x-javascript" 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/x-javascript" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/atom+xml" enabled="true" />
<add mimeType="application/xaml+xml" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
</httpCompression>
It would be MUCH easier to change your web.config then trying to figure out what web servers applicationhost.config file is incorrect but unfortunately it doesn't work
That being said IIS Express is setup "incorrectly" by default. It gives javascript files a mimetype of "application/javascript" but only compresses javascript files that come across as "application/x-javascript". I don't know if IIS (not express) ever comes defaulted this way.
You could try adding the doDynamicCompression attribute with a value of true to the urlCompression attribute.
<urlCompression doDynamicCompression="true" />
My website is hosted on an Azure WebRole and the content is fetched using Azure CDN.
The main HTTP request itself is compressed, but the static content (css & js are the main issue here) isn't.
The request is sent with 'Accept-Encoding: gzip,deflate,sdch' header, but the response is missing the 'Content-Encoding: gzip' and 'Vary: Accept-Encoding' headers.
It's important to note that this happens when fetching the content both from and the CDN and directly from the WebRole.
These are the relevant web.config sections:
<urlCompression doDynamicCompression="false" doStaticCompression="true" />
<httpCompression directory="%SystemDrive%\inetpub\temp\IIS Temporary Compressed Files" noCompressionForHttp10="false" noCompressionForProxies="false">
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" />
<dynamicTypes>
<add mimeType="*/*" enabled="false" />
</dynamicTypes>
<staticTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/svg+xml" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
</httpCompression>
As you can see in the config, I've enabled compression for proxies and for HTTP 1.0, but it doesn't seem to be the problem.
Anyone has an idea what's wrong here?
I created the default MCV4 website and hosted in my local IIS8 in widows 8 system under default web site.
http://localhost/MyWesite
in IIS manager "Compression" enabled dynamic content compression and static content compression. also disabled file size limit for compression so all js file sized are considered for compression (still gzip compression did not happen)
Is this the only system level gzip configuration?
Then next I tried to do website level change. I also edited the applicationHost.config file in C:\Windows\System32\inetsrv\config below are the change I did
<section name="httpCompression" allowDefinition="MachineToApplication" overrideModeDefault="Allow" />
in the web.config file I added the following
<system.webServer>
<httpCompression>
<staticTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</staticTypes>
<dynamicTypes>
<add mimeType="text/*" enabled="true" />
<add mimeType="message/*" enabled="true" />
<add mimeType="application/javascript" enabled="true" />
<add mimeType="application/x-javascript" enabled="true" />
<add mimeType="image/jpeg" enabled="true" />
<add mimeType="*/*" enabled="false" />
</dynamicTypes>
<scheme name="gzip" dll="%Windir%\system32\inetsrv\gzip.dll" dynamicCompressionLevel="4" />
</httpCompression>
</system.webServer>
After doing this I restarted iis just in case. On loading the webpage no js file or html document got gziped.
Probably you have already fixed this issue, it just happened to me and I found this while looking for the error. I had the exact same web.config configuration (worked perfectly on older webserver with IIS 7.5).
I found that you need to go to Server Manager and make sure that you have setup the Dynamic Content Compression feature, under Web Server => Web Server => Performance.
