httpCompression not work inside web.config

Question

Is their anyway to make httpCompression work from inside web.config ?

i try to add this in my web.config but it's does nothing :

<httpCompression>
  <dynamicTypes>
    <clear />
    <add mimeType="text/*" enabled="true" />
    <add mimeType="application/json" enabled="true" />    
    <add mimeType="application/javascript" enabled="true" />
    <add mimeType="*/*" enabled="false" />
  </dynamicTypes>
  <staticTypes>
    <clear />
    <add mimeType="text/*" enabled="true" />
    <add mimeType="application/javascript" enabled="true" />
    <add mimeType="*/*" enabled="false" />
  </staticTypes>
</httpCompression>

It is by design. Please upgrade to IIS 10. – Lex Li Mar 07 '18 at 15:30 — Lex Li, Mar 07 '18 at 15:30
in IIS 10 we can change it in the web.config ? – zeus Mar 07 '18 at 15:35 — zeus, Mar 07 '18 at 15:35
yes, IIS 10 supports that fully. – Lex Li Mar 07 '18 at 15:47 — Lex Li, Mar 07 '18 at 15:47

Overriding compression related settings in web.config is considered a new addition in IIS 10,

https://blogs.msdn.microsoft.com/friis/2017/09/05/iis-dynamic-compression-and-new-dynamic-compression-features-in-iis-10/

So to answer your question, you have to upgrade to IIS 10.

@MaximMazurok that's not surprising, as the whole discussion (either here or in the Microsoft employee blog post) only covers basic elements like `dynamicTypes`. It is possible that overriding `scheme` in `web.config` is ignored by IIS. – Lex Li Jul 06 '21 at 14:34
That makes sense... Could you please take a look at my question regarding this matter? https://stackoverflow.com/questions/68266508/how-to-disable-brotli-httpcompression-in-iis-10-on-the-site-web-config-level – Maxim Mazurok Jul 06 '21 at 15:12

@MaximMazurok yes, I saw that but I have nothing more to comment. You have to reach out to Microsoft. – Lex Li Jul 06 '21 at 15:49
