Description
The following comment:
If the directive is specified on the server level, its value is only used if a server is a default one. The value specified also applies to all virtual servers listening on the same address and port.
found in:
http://nginx.org/en/docs/http/ngx_http_core_module.html#underscores_in_headers seems to indicate that the underscores_in_headers directive can only be used at the server block level if the server block is the default server. Our testing seems to show it can be used for any server block and only affects that particular server block. Is this comment maybe an old comment for a previous version of NGINX+?
Note:
See TracTickets
for help on using tickets.
The comment is an inaccurate attempt to explain that
underscores_in_headersshould not be relied on in non-default virtual servers, as the value from the default server block might still apply when parsing a particular header, see ticket:1523#comment:4 for details.
