Hi All,
Recently we had VM migration from an old location to another one. The migration cloned one branch of the whole architecture as the following: author -> publisher -> dispatcher. Nothing changes except the new clone has a new domain name. Now we found a problem, the dispatcher doesn't cache.
We can authorize contents from author, the contents will be replicated all the way to the dispatcher, but the dispatcher always skips itself and tries to get contents from the publisher. For instance, if we create a file abc.html directly in the dispatcher, it will report a 404 error because it doesn't exist in the publisher. If we delete a cached file in the dispatcher, say xyz.html, we can get the content directly from the publisher but no xyz.html created in the dispatcher. At last, if we shut down the publisher, we will see "The proxy server received an invalid response from an upstream server.", a Bad Gateway message.
Any help will be appricated!
Kevin
