6.6.16.0: Properties of virtual hosts

Aliases
Specifies one or more DNS (Domain Name Service) aliases for the virtual host.

Aliases must be unique within the administrative domain. If two virtual hosts have the same alias, when a request arrives for that alias, the results will be unpredictable. The request could be routed to either host.

Each alias has the format name:port. If the port is not specified, port 80 (the Web server port) is assumed.

Resources such as servlets, Web pages, and JavaServer Pages (JSP) files can be associated with a virtual host. When a resource associated with a virtual host is served, an alias of the virtual host comprises part of the resource's served path.

For example, http://myalias:9876/servlet/snoop might be the served path of the snoop servlet residing on a virtual host with the alias myalias on port 9876.

Aliases must be unique within the administrative domain -- two virtual hosts cannot have the same alias.

Default Virtual Host
Indicates whether this virtual host is the default virtual host. The value can be true or false.

MIME Table Parameters
Specifies the MIME Type/Subtype pairs to recognize.
  • MIME Type - The MIME Type, such as text, image, or application
  • Extension - The MIME Subtype, such as html, gif, or exe

When Application Server recognizes a MIME type, the servlet associated with that MIME type is invoked as a filter. (Use the Filters property of the Web application to correlate MIME types with particular servlets).

New in Fix Pack 2 Each Web application has its own MIME settings that take precedence over settings at the virtual host level (local scope).

Virtual Host Name, Virtual Host
Specifies the name by which to administer the virtual host. The name must be unique within the administrative domain containing the virtual host.
