Dear all,
just by trying the example of the documentation [1] (at least since 10.4+) you should be able to verify that the response contains all headers with lower-case names.
I think a client should not take the freedom to alter HTTP responses if this is not strictly required. What is the concrete reason for this behaviour?
hHanks,

Hi Marco,
I am not 100% sure, whether BaseX or the Java HTTP Client actually does the conversion, but it might be due to the fact, that we use the new Java HTTP Client since BaseX 10.
By default, it uses HTTP/2 where headers must be lower-case while in versions before HTTP/2 the headers are defined to be case-insensitive. Hence, my guess is: The conversion happens because it must in HTTP/2 while it’s valid in HTTP/1/1.1. I hope this doesn’t cause too much trouble on your end.
Best Michael

Hi Marco,
As Michael has already confirmed, BaseX 10 and later is based on the new Java HTTP Client, which returns all response header field names in lowercase as required by HTTP/2 [1].
Best, Christian
