… should read/write headers values as case insensitive

Currently only the getValues method use case insensitive per default, all other are case sensitive.

This fixes problems behind a nginx reverse proxy, where "X-Forwarded-Proto" header is set as "X-forwarded-proto" (#1191).
The X-Forwarded-For is working because it's read in restlet with getValues method.

Hi @notz , this is not so easy to change the default read option as this class is also used elsewhere.
I have to check more deeply.
I think we can make sure that the framework internally reads the header in the right way. In the cases you read the headers from your own code, is it possible for you to read using the value in the case-insensitive way?

@jlouvel Any chance to get this into 2.6?

Hi @notz We could tackle this change in version 2.7 which along with 3.0 version will give us the opportunity to change the Restlet API and core behavior as needed, while 2,6 should stay as close as possible to 2.5 to streamline upgrades of production apps to Java 17 and Jakarta.
