Lucee GZip compression option ignores Accept-Encoding HTTP header

Description

The Accept-Encoding header tells the server what it is capable of decoding. Lucee seems to ignore this header because it should only Gzip the output if the header `Accept-Encoding: gzip, deflate` is sent along with the request. However regardless if this header is sent or not if the option is enabled Lucee will always Gzip the response.

I don’t think it is working then. Use curl to make a request both with and without the header and you will see that without the header the response is empty but when adding the header you see the Gziped data

there is a check for this header

https://github.com/lucee/Lucee/blob/5.3/core/src/main/java/lucee/runtime/writer/CFMLWriterImpl.java#L408

does it also happen if you bypass any webserver and hit tomcat directly, i.e on port 8888?

yes that is correct. I set mine inside the GUI rather than doing it inside of Application.cfc

Do you mean when {{this.compression = true; }} is set in application.cfc?
