Thanks. It is not really possible to comment without knowing how you set things up.

With proper set up for the CDN to serve only static content (images, clientscript (java and css files)), there is no reason for any security token errors.

First, you should outline all the steps you have done so far.

For us, we simply change the style variables, change the location of smilies etc in the AdminCP and add a few replacement variables for client script.

Another method which works equally well, is to use Apache mod_rewrite, but we don't do it that way.

OBTW, in case you did not read this blog post over at The UNIX and Linux Forum about MaxCDN and their initial impressions on their vB forum:

Just wondering if anyone has been able to come up with a solution for moving the attachment directories out to S3 or another CDN?

There are a number of ways to do this. Perhaps the easiest way is to simply edit the postbit_attachment template and change:

You could also do this with RRs, but you would need to be careful not to replace the code which uploads the attachment; so I advise you to just edit the template that displays the attachment (above).
