debug headers with nginx

THIS IS A DRAFT

descr

debug the headers you’re receiving from your CDN provider – e.g. you need to check you’ve got x-request-id

you probably don’t have debug enabled

# empty output
nginx -V 2>&1 | grep '^configure arguments' | grep with-debug

so you need a custom built nginx for that

./configure ... --with-debug

on test-nginx-backend

error_log /var/log/nginx/error.log debug;

nginx -t
nginx -s reload
#nginx -s reopen
tail -F /var/log/nginx/error.log | grep 'http header'

from pfsync1

curl -I -H 'test-header: test string' THAT_ORIGIN
