Root Cause

add_header directives in parent block not inherited when child has own add_header.

generic

Workarounds

  1. 90% success Use ngx_headers_more module: more_set_headers always inherits
  2. 85% success Include shared header file in each location block

Dead Ends

Common approaches that don't work:

  1. Duplicate all headers in every location block 72% fail

    Maintenance nightmare

  2. Use server-wide headers only 68% fail

    Loses per-location customization
