Seems to not be working in that there is no error, but my Rails app is  
not keeping track of any session. Fragment cache is working, however. I  
have tried many different ways, but just can’t get this to work. My  
memcached-vv also looks normal. Can someone please help me, or tell me  
where to start looking.

evironment.rb:

require File.join(File.dirname( **FILE** ), ‘boot’)  
require\_gem ‘memcache-client’

memcache\_options = {  
:compression =\> false,  
:debug =\> false,  
:namespace =\> ‘domain’,  
:readonly =\> false,  
:urlencode =\> false  
}  
memcache\_servers = “localhost:11211”

Rails::Initializer.run do |config|  
config.action\_controller.session\_store = :mem\_cache\_store  
config.action\_controller.fragment\_cache\_store = :mem\_cache\_store,  
memcache\_servers, memcache\_options  
#config.action\_controller.fragment\_cache\_store = CACHE, {}  
#ActionController::CgiRequest::DEFAULT\_SESSION\_OPTIONS.merge!({  
‘cache’ =\> CACHE })

require ‘hodel\_3000\_compliant\_logger’  
config.logger = Hodel3000CompliantLogger.new(config.log\_path)  
end

cache\_params = \*([memcache\_servers, memcache\_options].flatten)  
CACHE = MemCache.new \*cache\_params  
ActionController::CgiRequest::DEFAULT\_SESSION\_OPTIONS.merge!({ ‘cache’  
=\> CACHE })

ActionMailer::Base.delivery\_method = :smtp

ActionMailer::Base.server\_settings = {  
:address =\> “[mail.domain.com](http://mail.domain.com)”,  
:port =\> 25,  
:domain =\> “[domain.com](http://domain.com)”,  
}

ActionMailer::Base.perform\_deliveries = true  
ActionMailer::Base.raise\_delivery\_errors = true  
ActionMailer::Base.default\_charset = “utf-8”

require ‘RMagick’  
include Magick  
require ‘cgi’  
require ‘cached\_model’  
require ‘misc’

Hi,

Above code is working fine,

you assign the memcached server where you run memcache server

memcache\_servers = “localhost:11211”

above line you replace localhost as IP(i.e,)where memcache server  
running  
ex:memcache\_servers = “168.162.10.26:11211” – like this

and start memcache server using this cmd

memcached -d -m 256 -u nobody -p 11211 -l 168.162.10.26

any doubt in this mail me.

regrads,

It seems to be working except that I am getting key too long error. If  
possible, can you tell me what I am missing?

I will really appreciate your help.
