CDN replacement variable for VB CMS attachments

Hi,

Could you please show me how to do that.

I tried to add replacement variables:

Search for text:
src="http://mywebsite.com/forums/content/attachments/
Replace with text:
src="http://cdn.mywebsite.com/content/attachments/

and it did not work.

You should use the vbseo CP interface in 3.6 to handle attachments.

I am using the vbseo CP interface options, forums attachments are redirected correctly (using MaxCDN by the way). But CMS attachments are not.

I also tried this in advanced setting: 'content/attachments'=>'http://cnd.mywebsite.com/content/attachments/
but it did not work.

Does it make any difference if the attachments folder is actually outside of web root? My attachments don't seem to be getting picked up by the CDN either. All other file types work fine.
