Customising the CMS

Silverstripe CMS on a clustered server environment

I've built a silverstripe site which is being hosted on a distributed infrastructure. Now it's deployed for testing I'm having issues with maintaining Session states across the boxes.

I've implemented memcache for the frontend stuff, and that is working well.

However, when a user logs into the CMS their logged in status is not being maintained. I presume the stuff that handles this is using Session??

Where can I switch the user authentication to instead use my Memcache server??

From memory I resolved what may be the same problem as follows (in mysite/_config.php).

   // If this is not set, the path in cookie will be empty and logins
   // will fail

For reference, I solved this issue, by overriding the framework/security folder by copying it into mysite/ .

I then did a find replace on all instances of Session::{function-name}, and replaced them with an appropriate Memcache function.

I also had to instantiate the Memcache servers in Main.php.

Fun times...

But it works.

I'm glad you got it solved. You may want to have a look at Object::useCustomClass(). That way you could use your own customised version of the Session class that makes use of memcached without having to hack the framework.
