gzip compression for HTTP 1.0 proxy requests on Azure Web Sites

Question

Is there any way to get Azure Web Sites to serve gzip'ed content for requests from a HTTP 1.0 proxy like Amazon Web Services CloudFront? Consider a request like this:

curl -I -H "accept-encoding: gzip,deflate,sdch" -H "Via: 1.0 {foo.cdn.net}" -0 http://{fooproject}.azurewebsites.net/

It seems that the general way to accomplish is to add the following element to system.webServer:

<httpCompression noCompressionForHttp10="false" noCompressionForProxies="false" />

It also seems that httpCompression is only valid in ApplicationHost.config and not web.config which means that it's not overwriteable on Azure Web Sites.

Any suggestions for workarounds?

Answer 1

IIS won't compress for HTTP/1.0 requests. You can override this behaviour by setting:

appcmd set config -section:system.webServer/httpCompression /noCompressionForHttp10:"False"
