Many people do it the complicated way: setcookie 'name', 'content', time ; But why do you make it so complicated and risk it not working, when the client's time is wrong? Why fiddle around with time ; Here's the easiest way to unset a cookie: setcookie 'name', 'content', 1 ; Thats it. Note when setting "array cookies" that a separate cookie is set for each element of the array. On high traffic sites, this can substantially increase the size of subsequent HTTP requests from clients including requests for static content on the same domain. More importantly though, the cookie specification says that browsers need only accept 20 cookies per domain. This limit is increased to 50 by Firefox, and to 30 by Opera, but IE6 and IE7 enforce the limit of 20 cookie per domain.

This works fine, except when we want to pass more information with the click of this particular button. Imagine a scenario where you're dealing with user management in some administrative interface. You are presented with a list of user names queried from a database and wish to add a "Delete" and "Modify" button next to each of the names in the list. Naturally the 'value' of our buttons in the HTML form that we want to display will be "Delete" and "Modify" since that's what we want to appear on the buttons' faceplates.
Starting from version 4. If you are installing Samba in a production environment, it is recommended to run two or more DCs for failover reasons. The Samba AD provisioning process creates the AD databases and adds initial records, such as the domain administrator account and required DNS entries. The samba-tool domain provision command provides several parameters to use with the interactive and non-interactive setup. For details, see:. For example:. If you need more than one reverse zone multiple subnets , just run the above command again but with the data for the other subnet. During the provisioning, Samba created a Kerberos configuration file for your DC. Copy this file to your operating system's Kerberos configuration. Samba does not provide System V init scripts, systemd , upstart , or other services configuration files.
