We’ve been using memcached to store sessions across our mongrel  
cluster but we’ve noticed that when apache switches us to a different  
mongrel our session dies and we get logged out. Further, when I switch  
mongrels manually (using different ports) the same thing happens. I’ve  
been hunting around for the last couple of days on this but to no  
avail so I thought I would ask the experts.

There are two versions, the version from err’s blog and an updated one  
that seems like it’s more in line with memcache-client 1.3.0 options.  
They perform exactly the same.

Also below is a sample dump from memcached -vv

Thanks in advance for any advice!

Sincerely,  
Chuck V.

=====================

Here is my environment.rb:

Rails::Initializer.run do |config|  
config.action\_controller.session\_store = :mem\_cache\_store if  
RAILS\_ENV = ‘production’  
config.plugins = [“engines”,"\*"]  
end

memcache\_options = {  
:namespace =\> “nef\_#{RAILS\_ENV}”,  
:readonly =\> false,  
:multithread =\> true  
}

CACHE = MemCache.new(‘localhost:11211’, memcache\_options)

ActionController::Base.session\_options[:expires] = 1800  
ActionController::Base.session\_options[:cache] = CACHE

— OR —

Rails::Initializer.run do |config|  
config.action\_controller.session\_store = :mem\_cache\_store if  
RAILS\_ENV = ‘production’  
config.plugins = [“engines”,"\*"]  
end

require ‘memcache’

memcache\_options = {  
:c\_threshold =\> 10\_000,  
:compression =\> true,  
:debug =\> false,  
:namespace =\> “nef\_#{RAILS\_ENV}”,  
:readonly =\> false,  
:multithread =\> true  
:urlencode =\> false  
}

CACHE = MemCache.new memcache\_options  
CACHE.servers = ‘localhost:11211’

ActionController::Base.session\_options[:expires] = 1800  
ActionController::Base.session\_options[:cache] = CACHE
