The following nginx config is regarded as invalid via { nginx -t }. However the config will become valid if removing the 2nd server block.
Is the "xxx*" be valid in nginx conf?

events {}
http {  
  access_log off;
  server {
    server_name xxx*;
    location = /abc { return 200; }
  ## START: Remove the following server block will make nginx valid ##
  server {
    location = /abc { return 200; }
  ## END ##

Wildcards are only allowed as the first or the last part of the name, see docs. With only one server block names are not checked at all, hence the configuration with only one server is accepted.

If you want to do complex checks on names, consider using regular expressions instead.

Note: See TracTickets for help on using tickets.
