UEFI HTTP Boot fails when running a web server behind HAProxy (or other proxy) to provide initial ramdisk and kernel.

HAproxy (and probably other proxies) is changing HTTP response headers to lowercase. On the other hand, grub2 uses a case-sensitive comparison for the Content-Lenght header leading to prematurely closing the connection and leaving the client with a partially downloaded initrd/kernel.

A possible fix for this issue is to use a case-insensitive comparison for that header (or any headers where necessary).

A simple fix is available in the attached path file.
Thank you.

Best regards,
Dimitar Nikov
