Class VHostItem

java.lang.Object
  tigase.db.comp.RepositoryItemAbstract
      tigase.vhosts.VHostItem

All Implemented Interfaces:

RepositoryItem

public class VHostItem
extends RepositoryItemAbstract

Objects of this class represent virtual host with all hosts configuration settings. In most cases simple domain name string is not enough to deal with the virtual host. VHost can be enabled/disabled. Can be available to selected server components only and so on. Therefore every time there is a detailed information needed for a vhost this classed must be used. This class has it's own XML representation which can be used for creating an instance of the class or can be exported to the XML form for permanent storage:

From the init.property file it is also possible to set additional parameters for the vhost. By default everything is enabled and max accounts set to unlimited. In the example below we configure 2 domains: devel.tigase.org and test.tigase.org. For the first domain there are no additional settings, hence the domain has everything on by default, whereas the second has everything switched off and max user accounts set to 100.

 --virt-hosts = devel.tigase.org,test.tigase.org:-anon:-register:max-users=100
 

It also possible to set forwarding for the domain:

 --virt-hosts = test.tigase.org:pres-forw=lpart@domain/res:mess-forw=lpart@domain/res
 

Please note, forwarding address set this way cannot contain any of characters: [,:=] The order features are set for domain is unimportant. Created: 22 Nov 2008
