topics related to TCP/IP configuration on NonStop systems, see the TCP/IP
Configuration and Management Manual.
Assigning Servers to Specific IP Addresses
You can limit a server to accept connections on only one IP address and assign each
of multiple servers running on the same host to a different IP address.
You assign a server to a specific IP address by specifying an Accept directive with the
-address option in the server configuration file (httpd.config).
For example, you could specify the directive
Accept -transport /G/ZTC0 -address 16.11.96.5
in the configuration file of one of two servers, to limit this server to accepting
connections only on IP address 16.11.96.5.
Similarly, you could specify the directive
Accept -transport /G/ZTC0 -address 16.11.96.6
in the configuration file of the other server, to limit this server to accepting connections
only over IP address 16.11.96.6.
You can specify a host name instead of an IP address in an Accept directive by using
the -address option. The host name specified must correspond to a local IP address,
and then the server automatically uses that IP address. For example:
Accept -transport /G/ZTC0 -address www.widgets.com
Again, each of the servers assigned a different IP address is completely independent
of the others. Each has its own configuration file, log files, and content areas.
For further details on the Accept directive, see Accept on page A-2.
Implementing Virtual Hosts
Another way to configure a server for multiple-host support is to configure a single
server process into virtual hosts, with each virtual host checking for requests on a
different IP address or port. Configuring a single server process to support multiple
virtual hosts involves:
•
Establishing virtual IP addresses, as described in Establishing Alias IP Addresses
on page 7-44
•
Setting Up Virtual Hosts on page 7-45
Setting Up Virtual Hosts
You can cause one iTP Secure WebServer to function as multiple servers by setting up
multiple virtual hosts. Each virtual host can be configured to check for requests on a
different IP address or port and can be mapped to host a specified region on the
server.
