Why the `memcached_servers ` do not have `http://` in front of the address?

In the /etc/glance/glance-api.conf, why the memcached_servers do not have http:// in front of the address, you see the auth_uri and auth_url all have.

[keystone_authtoken] 
＃... 
auth_uri  =  http：// controller：5000 
auth_url  =  http：// controller：35357 
memcached_servers  =  controller：11211 
auth_type  =  password 
project_domain_name  =  default 
user_domain_name  =  default 
project_name  =  service 
username  =  glance 
password  =  GLANCE_PASS
Solution

  • Presumably because they don't communicate over http?

    https://github.com/memcached/memcached/blob/master/doc/protocol.txt

    Memcache appears to communicate over a custom protocol over TCP.
