WA Profile affects BACK button behavior

I have a site that I made a simple policy from scratch to server images. I simply created a policy with a Matching Rule for Extension to look for jpg, gif, or PNG. That worked just fine. I then wanted to add js and css files to the mix. After doing some more reading, I read that I should really copy an existing policy and modify that. Hence, I made a copy of the Level 1 (or Level 2) policy--I forget--and set that to server images and "Includes"(js and css). That does indeed cache the content, but I now get strange behavior in that on some pages that do a post, when I use the back button, I get the dialog on the browser saying you are resubmitting the data. This does not happen if the WA is out of the picture or I am running on that original homegrown profile.

 

 

Does anyone know what would change that behavior?

 

 

Thanks,
