Keep-Alive

Disabling keep-alive might help your server if you suffer from a large number of open file descriptors.

• defaults:

server.max-keep-alive-requests = 128
server.max-keep-alive-idle = 30
server.max-read-idle = 60
server.max-write-idle = 360

• less...

server.max-keep-alive-requests = 8
server.max-keep-alive-idle = 8

• Disabling keep-alive

server.max-keep-alive-requests = 0

modules

aio-sendfile

./configure --with-openssl --with-linux-aio

• in lighttpd.conf

server.network-backend = "linux-aio-sendfile"

sec download

 secdownload.secret        = <string>
 secdownload.document-root = <string>
 secdownload.uri-prefix    = <string>  (default: /)
 secdownload.timeout       = <short>   (default: 60 seconds)

secdownload.secret          = "password"
secdownload.document-root   = "/export/mediaroot/auth/"
secdownload.uri-prefix      = "/dl/"
secdownload.timeout         = 120

• php then..

<uri-prefix>/<token>/<timestamp-in-hex>/<rel-path>

PHP Example

  <?php

  $secret = "verysecret";
  $uri_prefix = "/dl/";

  # filename
  # please note file name starts with "/" 
  $f = "/secret-file.txt";

  # current timestamp
  $t = time();

  $t_hex = sprintf("%08x", $t);
  $m = md5($secret.$f.$t_hex);

  # generate link
  printf('<a href="%s%s/%s%s">%s</a>',
         $uri_prefix, $m, $t_hex, $f, $f);
  ?>
