I am not using openresty as a proxy but as a web server. Twitter
requests an image, and it sends the HTTP request with header
"Finagle-Ctx-com.twitter.finagle." This makes nginx abort the
operation.
I need the operation to be completed as designed. For that, I added
underscores_in_headers (on or off) makes no difference.
ignore_invalid_headers on (on or off) makes no difference
any ideas?
