Upon loading your address I get a page saying "The southern Porsche Car Club" (although there seem to be a missing image).
Have you tried clearing your browser cache?
Is A Change Applied Immediately On the Web As Soon As New Files Are Uploaded ?
Yes, but if a person viewing your website has the site cached, as you experienced, it will not update. The only exception would be a proxy server, where the proxy could cache before it gets to the user. But 99% of the time, updates should be instant.
You may want to consider using meta tags to force your site not to cache until you're done developing it.
Thank you.
So I'm wrong in thinking that clicking refresh in a browser should always bring up the new page?
