About alternate website addresses
Web servers can be configured in a variety of ways to respond to varying user needs. One
common part of web server configuration is the mapping of web addresses to either different
IP addresses (often for either load balancing or localization issues), or multiple web addresses
pointing to a single IP address. The following common web server configurations involve
URL mapping.
Multiple DNS aliasing
occurs when two or more domain name server (DNS) aliases point to a
single server (for our purposes, a single server consists of a single IP address). When connecting to
a server configured with multiple DNS aliases, Contribute views the defined website and the
aliases as different websites, even though from the users’ perspective they are the same.
For example, if your server hosts the website www.carsonline.com, and you set up two additional
web addresses that refer to that same website (for example, www.cars.com and www.mycars.com),
you must configure Contribute to recognize these different web addresses as the same website.
Virtual server
is when two or more DNS aliases point to the same server, but are viewed by the
user as different websites. When a server configured in this way receives a request to retrieve a web
page, it serves different pages depending on the address used in the request. There are two types of
virtual server configurations:
•
DNS-based virtual servers use a single IP address that has two or more DNS aliases pointing to
that address. In this configuration, the web server differentiates the page request based on the
web address, serving different pages to the different addresses.
•
IP-based virtual servers use multiple IP addresses to differentiate websites.
A common use of virtual server configurations is to provide localized content to different
geographic locations. For example, a news website might provide different local information to
users viewing the website based on their location.
Port numbers
are often used to further divide a domain name into multiple websites. Often this is
to allow the website to provide different software functionality based on a port that may be
listening for incoming requests.
A web address that uses a different port number is considered to be a different website. However,
this is not always the case. As with web server configurations using multiple DNS aliases, it’s
important that you map host names using different port numbers to the correct website.
For example, if your organization’s website can be accessed through two different web addresses
differentiated by port numbers, then you must add these web addresses to the Alternate addresses
field. In this example, assume that your organization maintains the following web addresses:
www.cars.com
www.cars.com:8080
Both of these web addresses point to the same website, with the exception that those sites using
port number 8080 read the browser’s cookie file to check whether the visitor is a new or returning
user. If the user is already registered, the website appears without prompting for registration. If a
user is new, a dialog box appears requesting the user to register to gain access to the website.
