Re: Is it possible to set a ddns hostname to access a name-based virtual host?
Hi, Is it possible to set a ddns hostname, say through http://www.changeip.net/ , without using *some_domain* itself, to access this file? http://www.changeip.net/ Not entirely sure what you are actually trying to achieve. Could you provide a concrete example of the situations you are trying to achieve? If you wan't the file to be accessible through multplile hosts (differentaited through the host header, you need to configure the webserver to handle these names. If you wan't a hostname to be updated automatically when the server IP address changes, you need to configure the approriate service to connect to the ddns service. If you want specifics about the ddns service provider, you should ask them. From changeip.net: Dynamic DNS gives you the ability to redirect your domain name to anywhere at any time. Why wait 3 days for your ISP to update their DNS records when you can do it yourself, in seconds. Get your free name now and it will be working within 5 minutes! Hope this helps.

You can specify a domainalias for every virtualhost in the apache configuration (other http servers should support similar functionality) This has nothing to do with DNS since all dns does is translate the hostname you type in to an IP address the computer uses to connect to. Every http request contains a 'host' header that is used by the webserver to determine the documentroot to serve. Hope this helps.

Is this possible? Generally, no. Virtual hosting involves setting, in almost all cases, a unique document root for each virtual host. If you reference a file or location via a URI that uses a different hostname, then it either matches a different virtual host, or matches the default virtual host, but in either case the document root is almost certainly different, and thus the relative path (/pdf/PRB/v1/i1/P1_1 in your case) almost certain does not translate to the correct absolute path to get the right file or get you to the right generator, whatever the location references and/or triggers to send back content. You *must* reference the location using the same URI if you expect to see the same expected results.

DNS can only control what IP address the client connects to. It doesn't have any effect on the Host: header that is sent in the HTTP request, and that's what a webserver uses to identify the target site, in a named-based virtual hosting context. I think you want to use a proxy with URL-rewriting capability. SQUID seems to be capable of this.

Re: Question re separating caching and authoritative servers

If the caching server locates your own authoritative data through normal delgation channels, and cannot reach the roots and TLDs, then your own local clients could be unable to resolve names of local servers, etc. Any especially good or bad practices? Things that have worked well or poorly? Right now, I'm leaning toward having the caching server transfer key zones. That's reasonable. The other alternative is to set up stub zones which short circuit the resolution process.
