Clear your cache and cookies on iPad
In the Safari app , you can erase your browsing history and data to clear the cache on your iPad. This action removes the history of websites you visited and recent searches from your iPad.

Note: Clearing your browsing history in Safari doesn’t clear any browsing histories kept independently by websites you visited, or your browsing history in other apps.
