Website appears in plain text without images after Sonicwall NSA firewall content filter has been allowed

The company I am doing work for have recently adopted Twitter.com as part of their marketing strategy and as a result the CEO needed access to the site.

It had previously been blocked by default but it now need to be added to the custom list within the Sonicwall content filter.

This did unblock the site but it was only showing the text of the site and not the text and images.

Can you guess what the problem is yet ?. Twitter.com uses another website to provide the images to it’s site i.e. twimg.com which is also blocked by default. Therefore, in order to resolve this problem you will need to also add ‘twimg.com’ to the filter aswell.

Although, this works for Twitter it is true of all sites that show as plain text. In order to find the site that contains the images just keep refreshing the page and make a note of the URLs that ‘try’ to load in the bottom left of the browser.
