Subject: [PATCH] http: Prepend prefix when the HTTP path is relative as done
in efi/http
There are two different HTTP drivers that can be used when requesting an
HTTP resource: the efi/http that uses the EFI_HTTP_PROTOCOL and the http
that uses GRUB's HTTP and TCP/IP implementation.
The efi/http driver appends a prefix that is defined in the variable
http_path, but the http driver doesn't.
So using this driver and attempting to fetch a resource using a relative
path fails.
