  <para>
   <function>Memcache::addServer</function> adds a server to the connection 
   pool. The actual connection is established on first use.
   The connection, which was opened using
   <function>Memcache::addServer</function> will be automatically closed at the
   end of script execution. Also you can close it with
   <function>Memcache::close</function>.
   You can also use the <function>memcache_add_server</function> function.
  </para>

  <note>
   <para>
    This function has been added to Memcache version 2.0.0.

     <listitem>
      <para>
       Number of buckets to create for this server which in turn control its
       probability of it being selected. The probability is relative to the
       total weight of all servers.

     <listitem>
      <para>
       Value in seconds which will be used for connecting to the daemon. Think
       twice before changing the default value of 1 second - you can loose all
       the advantages of caching if you connection is too slow.

      <para>
       Controls how often a failed server will be retried, the default value
       is 15 seconds. Neither this nor the <parameter>persistent</parameter>
       parameter has any effect when this extension is loaded dynamically
       via <function>dl</function>.
