Functional Details of Virtual Multihosting

The virtual multihosting feature works by specifying the DNS host and domain names or aliases, and then a target URL prefix where requests sent to that host name should be directed. As an example, suppose you have two mappings:

Mappings do not have to go root-to-root. You may specify an additional URL path prefix in the target URL:

The same technique applies to virtual domain mappings. For example, you could use:

The system will look at the HTTP “Host:” header. Based on that header, the system will choose the matching Virtual Multihosting mapping. If none of the multihosting mappings match, the server will continue looking at other mappings in the order that they appear in the configuration file, or perform no mappings if no matches are found. If no matches are found, the proxy will typically issue the “Proxy denies fulfilling the request” response.
