Hello,

My memcached seems to work OK for a single mongrel instance. When I  
move to  
a mongrel cluster, memcache seems to lose the session state between  
mongrel  
cluster instances.

I am using the standard memcached configuration (with memcache-client),  
as  
shown below. Any ideas?

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

require\_gem ‘memcache-client’  
Rails::Initializer.run do |config|  
config.action\_controller.session\_store =:mem\_cache\_store  
end  
memcache\_options = {  
:compression =\> true,  
:debug =\> false,  
:namespace =\> “pr-#{RAILS\_ENV}”,  
:readonly =\> false,  
:urlencode =\> false  
}  
memcache\_servers = [‘127.0.0.1:11211’]  
CACHE = MemCache.new(memcache\_options)  
CACHE.servers = memcache\_servers  
ActionController::Base.session\_options[:cache] = CACHE

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