+I've gone ahead and filed a bug on CGI.pm too:

+
+That'll be an interesting discussion as I'd suggest that HTTP_ headers are defined in the CGI specification as client headers and thus what `thttpd` is doing is wrong (i.e. mangling the client's own representation). Whether a CGI client should trust HTTP_ header over the server is probably already settled by convention.
