How does virtual host support work in Apache?

How does virtual host support work in Apache?

Using a wildcard (*) for the IP address in all of the VirtualHost directives makes this IP-based mapping irrelevant. When a request arrives, the server will find the best (most specific) matching argument based on the IP address and port used by the request.

What should I do if I have more than one Apache server?

If you are hosting more than one site on a server, then you most likely use Apache’s virtual host files to state which domain should be served out. Name based virtual hosts are one of the methods used to resolve site requests.

Can a virtual host share the same IP address?

Using this technique, many different hosts can share the same IP address. Name-based virtual hosting is usually simpler, since you need only configure your DNS server to map each hostname to the correct IP address and then configure the Apache HTTP Server to recognize the different hostnames.

How to disable default virtualhost in Apache2?

How to disable default VirtualHost in apache2? In apache2 by design, any http request with an unknown Host will be directed to the first loaded VirtualHost. Is there a way to disable this feature?

Can a virtual host have the same IP address?

Above we can see that even if the two virtual hosts have the same IP address, a different port is specified in the second example: 8080. In order for the server to be able to listen to that port we use the Listen 8080 directive. In this tutorial we saw how Apache virtual hosts work.

What does Apache mean by the vhost address set?

Collectively the entire set of addresses (including multiple results from DNS lookups) are called the vhost’s address set. Apache automatically discriminates on the basis of the HTTP Host header supplied by the client whenever the most specific match for an IP address and port combination is listed in multiple virtual hosts.

How are IP based virtual hosts used in httpd?

IP-based virtual hosts, as we already saw, are basically what the httpd server uses by default. When using them, the ability to serve multiple websites is based on the client request IP:PORT combination. It goes by itself that, to use this type of virtual hosts, a machine must have multiple network addresses.
