There has been some bruhaha over Google Web Accelerator and web applications. Google Web Accelerator works by "prefetching" pages in the background so clicking on a link results in a faster page load. Unfortunately, it blindly follows any link on the page, regardless of whether you've put a JavaScript confirmation on it. The practical upshot of this is that links to delete items may be followed, leading to simply viewing a list of items causing them to disappear. Fortunately, Google Web Accelerator uses the Mozilla Foundation's X-moz: prefetch HTTP header. So it can be detected and stopped with the following two lines in an .htaccess file:

RewriteCond %{X-moz} ^prefetch
RewriteRule ^.* - [F]

We have implemented this fix for the administration application in SyntaxCMS, so you can grab the latest copy of /syntax-cms/src/public/admin/.htaccess from the SyntaxCMS CVS repository on Tigris or, if you've modified that file, simply put the above two lines below RewriteEngine On in /public/admin/.htaccess on your installation.
