Httpd Proxy Configuration

Running several name-based web sites on a single IP address.

The parent re-reads its configuration files and re-opens its log files. As each child dies off the parent replaces it with a child from the new generation of the configuration, which begins serving new requests immediately. We can run a configuration file syntax test as follows: apachectl configtest apachectl -t.


Your server has multiple hostnames that resolve to a single address, and you want to respond differently for and

  • Edit the httpd.conf file in your Apache HTTP Server installation to configure the Apache HTTP Server plug-in. Open the httpd.conf file, if it is not already open. To proxy requests by MIME type, add an IfModule block that defines one of the following: For a non-clustered WebLogic Server: the WebLogicHost and WebLogicPort parameters.
  • Your HTTPD is configured to use modproxy to send client requests to JBoss Enterprise Application Platform servers or clusters, either in a standard or load-balancing configuration. To configure the JBoss Enterprise Application Platform to respond to these requests, refer to Section 13.2.11, “Configure the JBoss Enterprise Application.
  • An Apache httpd proxy server situated in an intranet needs to forward external requests through the company's firewall (for this, configure the ProxyRemote directive to forward the respective scheme to the firewall proxy). However, when it has to access resources within the intranet, it can bypass the firewall when accessing hosts.
  • Apache HTTP Server can be configured in both a forward and reverse proxy (also known as gateway) mode. An ordinary forward proxy is an intermediate server that sits between the client and the origin server. In order to get content from the origin server, the client sends a request to the proxy naming the origin server as the target.

Creating virtual host configurations on your Apache server does not magically cause DNS entries to be created for those host names. You must have the names in DNS, resolving to your IP address, or nobody else will be able to see your web site. You can put entries in your hosts file for local testing, but that will work only from the machine with those hosts entries.


The asterisks match all addresses, so the main server serves no requests. Due to the fact that the virtual host with ServerName is first in the configuration file, it has the highest priority and can be seen as the default or primary server. That means that if a request is received that does not match one of the specified ServerName directives, it will be served by this first <VirtualHost>.

The above configuration is what you will want to use in almost all name-based virtual hosting situations. The only thing that this configuration will not work for, in fact, is when you are serving different content based on differing IP addresses or ports.

You may replace * with a specific IP address on the system. Such virtual hosts will only be used for HTTP requests received on connection to the specified IP address.

However, it is additionally useful to use * on systems where the IP address is not predictable - for example if you have a dynamic IP address with your ISP, and you are using some variety of dynamic DNS solution. Since * matches any IP address, this configuration would work without changes whenever your IP address changes.
