Anyone have an idea why when I update the website I work on with an up to date banner that it still shows the old banner if it is accessed via
www.<companyname>.com
in all other variations ie
www.com.au, .com, .com.au, the new banner I placed in the images folder shows but with
www.com it shows an old banner. It even claims it is the same file with the same name in the same folder and yet it is not. Does it take sometime to update as with search engines?. I have checked on 3 different computers and it doesn't appear to be related to the cache.
