Requirements ------------ * libpcre * libgdbm or libmemcache (install the C client API,visit http://people.freebsd.org/~seanc/libmemcache/ and http://danga.com/memcached/apis.bml for detail.) 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.
