Memcached makes an excellent session store for Facebook applications. Unfortunately, it doesn’t work out of the box with Facebooker. See how to fix that inside.</p>
By default, the Memcached session store doesn’t allow session keys with dashes in them. Since Facebook session identifiers include a dash, this causes an immediate error. Luckily, there is a simple fix. Add the following code as either an initializer or to your environment.rb file to get your Facebooker sessions running with memcached.
# add - as an okay key class CGI class Session class MemCacheStore def check_id(id) #:nodoc:# /[^0-9a-zA-Z-]+/ =~ id.to_s ? false : true end end end end
