True, although the OP's lack of knowledge of "how" lead to the need to ask the question of "why". Thus my follow-up with a link for how. > > > Please provide a detailed description of how Tomcat function with > > useIPVHosts set to "true", or provide a link which does. > > I still think the existing wording is sufficient: > > "Set this attribute to true to cause Tomcat to use the IP address that > the request was received on to determine the Host to send the request > to." > > However, I presume you'd like additional wording to the effect that the > symbolic form of the IP address must be configured as the <Host> name > or an <Alias> thereof. > Yes, that would be nice, or even a reminder that names won't matter a bit. Some folks can be "a bit fick" on such things. All the posts I've seen inquiring about this feature seem to have missed that requirement as their starting point. Answers to some of those posts lead me to believe that there was some reverse resolution going on get the correct host (suggestions to add entries to the hosts file, etc.) Thus my original confusion and request for clarity. Allow me one more attempt at a clear doc? 1) If useIPVHosts=false (default), then the host header name determines <Host> for processing, or default host of the Engine. 2) If useIPVHosts=true, then IP address of request determines <Host> for processing, providing the IP is provided as the host name, or <Alias>. If not found, then default host of Engine applies. 3) Nothing external to server.xml matters to Tomcat in resolving <Host> for processing. Does that sound accurate?
