ngnix is not closing the socket after the connection finishes. I've googled and can't come up with anything to will tell nginx to close this connection, other than what I have below: keepalive_timeout 0.

In both the request and response headers, I can see Connection: close, but the socket still sits around in the TIME_WAIT state for about a minute.

tcp 0 0 127.0.0.1:80 127.0.0.1:40345 TIME_WAIT -

Here are the headers:

Request Headers: Connection: close Content-Type: application/x-www-form-urlencoded

Response headers: HTTP/1.1 200 OK Server: nginx/0.7.67 Date: Thu, 21 Apr 2011 15:34:31 GMT Content-Type: text/xml; charset=utf-8 Transfer-Encoding: chunked Connection: close

Part of my nginx config:

nginx config file: { ... keepalive_timeout 0; client_max_body_size 1M; fastcgi_read_timeout 60; fastcgi_send_timeout 60;

location ~ \.php$ {
    fastcgi_pass   unix:/tmp/php-fastcgi.sock;
    #fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_intercept_errors on; # to support 404s for PHP files not found
    fastcgi_param  SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include        fastcgi_params;
    fastcgi_param SERVER_NAME $host;
}

}

Waiting in TIME_WAIT state for few minutes is by design, please check following links for full description:
