Experience Manager Session Preview causes temporary files to be created for pages and binaries in my staging website (html pages published to Tomcat 7 - stuff like
index_789816da-1614-403f-9538-879fd05b9c57.html). Some of these are more than two days old - how do these get cleaned up? I checked all the web app config files, but can't find any settings there, or by searching the online docs.
UPDATE: There are some messages in the cd_preview log:
