VIRTUAL_HOST_DEFAULT

public static final VirtualHosts.VirtualHost VIRTUAL_HOST_DEFAULT

Default virtual host description (ie keyed from main site name) for default livery, etc. Default livery has normal navigation, advertising, layout, etc.

VIRTUAL_HOST_ALOHAEARTH

VIRTUAL_HOST_ZAPIX

public static final VirtualHosts.VirtualHost VIRTUAL_HOST_ZAPIX

Virtual host description and main name for ZAPix. ZAPix has a black background and minimalist furniture.

VIRTUAL_HOST_LOCALHOST

public static final VirtualHosts.VirtualHost VIRTUAL_HOST_LOCALHOST

Virtual host description and main name for localhost; primarily for testing. Usually standard livery, but need not be so.

VIRTUAL_HOST_127p0p0p1

public static final VirtualHosts.VirtualHost VIRTUAL_HOST_127p0p0p1

Virtual host description and main name for localhost as literal IPv4 address; primarily for testing. Usually standard livery, but need not be so.

VIRTUAL_HOST_cc1

public static final VirtualHosts.VirtualHost VIRTUAL_HOST_cc1

Virtual host description and main name for localhost as literal IPv6 address; primarily for testing. Usually standard livery, but need not be so.

canonicalVirtualHosts

public static final java.util.List<VirtualHosts.VirtualHost> canonicalVirtualHosts

Public (immutable) List of canonical "main" VirtualHost descriptions. In principle all host names or site URIs should map to one of these, and we may even force redirects and so on so that search engines and users learn and use these canonical versions.

This is not intended for fast lookup, and nothing is implied by the order of entries.

This should help:

• Reduce complexity of PG2K management, eg in deployment descriptors.
• Reduce redundant Web spider activity to deprecated host names.
• Improve load balancing by making better use of "core" aliases.

hostDetails

public static final java.util.Map<java.lang.String,VirtualHosts.VirtualHost> hostDetails

Public (immutable) Map from String normalised host name to VirtualHost. This is built from the main and alias host names.

For the moment this is hard-wired in; it may become loadable in GenProps in future.

public VirtualHosts()

getVirtualHostDetails

public static VirtualHosts.VirtualHost getVirtualHostDetails(java.lang.String serverHostname,
                                                             java.lang.String requestURI)

Lookup VirtualHost details by hostname and request URL; null if no match found. The hostname supplied is normalised before lookup.

Before a lookup by hostname is attempted, a match is attempted on the request URI iff the URI starts with the normal prefix for virtual sites. If a virtual host root is a prefix of the request URI then we force usage of the the virtual host livery.

Parameters:

serverHostname - the host name with which the page was fetched, as from request.getServerName()

requestURI - the within-host URI as from request.getRequestURI(), or null for a faster lookup just by normalised name
