natch: Your examples lend themselves to confusing answers, so I am changing the examples to use my own examples, which are of course totally clear and correct.Here's how the record in your zone file should look:foo            IN CNAME        lalala.bigpipe.com.The above (from foo all the way to .com.) should all be on one line. Note the . at the end is required.Now let's say this is the zone file on your web site, googoogaga.com. Now after this record takes effect, people can point to:http://foo.googoogaga.com/and they will get files from lalala.bigpipe.com, but their browser address bar will continue to show them foo.googoogaga.com. Nice, huh?You do not need to have access to the zone file on bigpipe.com; you only need to have access to put your content files you are serving onto lalala.bigpipe.com. Well, that is, unless you are using their content files.
