NGINX Compression – Enable Both Brotli and Gzip

gzipnginx

Is it possible to enable both gzip and brotli compression in NGINX?
If the client supports both then return brotli, if only gzip / brotli then return the specicfied, and else if no support for gzip / brotli return plain text

Best Answer

One of the first articles I found when searching online for nginx and brotli, is this link. It kinda answers your question — I think:

Browsers which supports brotli send ‘br’ along with ‘gzip’ in accept-encoding request header. If brotli is enabled on your web server, you will get response in brotli compressed format.

This means to me that if the client supports both, brotli is preferred over gzip.

Also note that "Brotli or gzip should not be used for binary files like JPEG, PNG, MP4."

IIS Compression: Enable GZIP and DEFLATE using Powershell

Your initial line of attack with PowerShell is to use WMI. Unfortunately, the root\MicrosoftIisV2 namespace is set up with non-standard security settings which you can't change in PS (not in V1, at least, V2 may be different).

I would suggest looking at the IIS ADSI provider, specifically the IIsCompressionScheme object - http://msdn.microsoft.com/en-us/library/ms524574.aspx

You may be able to work with this in PowerShell by manipulating

$obj = [ADSI]"IIS://MachineName/W3SVC/Filters/Compression/Scheme"

However, ADSI is pretty evil, so you'll have a fairly steep learning curve.

Nginx is not using gzip to talk to backend servers

Nginx is a HTTP/1.0 reverse proxy, gzip compression was not in the HTTP specification until HTTP/1.1.

Thus nginx will not send gzip accept-encoding header because it simply doesn't accept it. The proper way to implement gzip handling in nginx is to either talk fastcgi to the backend or to gzip using nginx.
