Virtual Servers Overview
The default virtual server is set by connection group. You specify a default virtual
server when you create a listen socket. That becomes the default virtual server of
the connection group created by default for the listen socket. You can always
change the default virtual server. If the listen socket has a specific IP address
associated with it, this connection group is the only connection group for the listen
socket. If the listen socket listens on any IP address, each connection group you
create will have a default virtual server.
Virtual Server Selection for Request Processing
Before the server can process a request, it must accept the request via a listen
socket, then direct the request to the correct connection group and virtual server.
A connection group is first selected as follows:
•
If the listen socket is configured to listen on a particular IP address, it can
contain only one connection group, and that group is selected.
•
If the listen socket is configured to listen on
client connected is matched to the IP address of a connection group contained
by that listen socket. If no IP address matches, the default connection group

A virtual server is then selected as follows:
•
If the connection group is configured to only a default virtual server, that
virtual server is selected.
•
If the connection group has more than one virtual server configured to it, the

header is present or no URL host matches, the default virtual server for the
connection group is selected.
If a virtual server is configured to an SSL listen socket, its URL host is checked
against the subject pattern of the certificate at server startup, and a warning is
generated and written to the error log if they don't match.
After the virtual server is determined, the server executes the
virtual server class to which the virtual server belongs. For details about how the
server decides which directives to execute in
