Known Nginx problems

• WebDav module doesn't support propfind and open actions, it's not really usable
• If proxying a request from varnish backend health detection, Nginx returns error 499.
• mod_perl, don't get me started...
• Reload will not report configuration errors on command line, only on error.log (can be fixed in init.d scripts) - personnaly I always use restart
• Some errors are reported incorrectly or cryptically. This is common on configuration errors.
• Configurations are order sensitive - make sure upstreams are defined before proxy statements, watch out for conf.d/* inclusion order.
• On version 0.8.46 a bug associated with nested use of capture groups appeared:

location ~ /test([0-9]+)$ {
  if ($host ~ www\.([^\.]+)\.com) {
    set $domain $1;
  }
}
