Good morning,
Using ngx_http_request_t, how can I access a custom upstream header
within a
module, for example:
r->upstream->headers_in->xxx_my_header->value
No matter what I try, it doesn’t appear to be working

Obviously enough the r->upstream->headers_in structure won’t
contain any specific members for your custom header unless you
patch nginx.
If you want to search for a custom header within a module, you
have to iterate though &r->upstream->headers_in.headers list. See
e.g. ngx_http_upstream_header_variable() and
ngx_http_variable_unknown_header(), used to implement
$upstream_http_* variables.
