======================= Trigger before Download ======================= ------------------------- Module: mod_trigger_b4_dl ------------------------- :Author: Jan Kneschke :Date: $Date: 2004/11/03 22:26:05 $ :Revision: $Revision: 1.2 $ :abstract: another anti-hot-linking module .. meta:: :keywords: lighttpd, hot-linking, deep-linking .. contents:: Table of Contents Description =========== Anti Hotlinking: * if user requests ''download-url'' directly, the request is denied and he is redirected to ''deny-url' * if user visits ''trigger-url'' before requesting ''download-url'', access is granted * if user visits ''download-url'' again after ''trigger-timeout'' has elapsed, the request is denied and he is redirected to ''deny-url'' The trigger information is either stored locally in a gdbm file or remotely in memcached. Requirements ------------ * libpcre * libgdbm or libmemcache Options ======= :: trigger-before-download.gdbm-filename = "/home/weigon/testbase/trigger.db" trigger-before-download.memcache-hosts = ( "127.0.0.1:11211" ) trigger-before-download.trigger-url = "^/trigger/" trigger-before-download.download-url = "^/download/" trigger-before-download.deny-url = "http://192.168.1.5:1025/index.html" trigger-before-download.trigger-timeout = 10 If both trigger-before-download.gdbm-filename and trigger-before-download.memcache-hosts is set gdbm will take precedence. Installation ============ memcached should be started with the option -M as we don't want to remove entry if the memory is full.
