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).
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.
