Exclude Gravity Forms

There are a couple ways to do this, see this walkthrough. You can also go to the Advanced tab in the Super Cache Settings and use “Accepted Filenames & Rejected URIs” there is a text box under “Add here strings (not a filename) that forces a page not to be cached” that you can add permalink strings. For instance, if you have forms for user accounts under “/my-accounts/” you can use that string here and all pages with that string in the permalink will not be cached.
