    I am having an issue with the cache file returning after deleting them. Not the file in the sub folder but mis files that are just under the cache folder. I have 260+ files that will not go away. The number has grown over the past few week. even tried unlink and reklink with no help.
    Not sure where it is pulling the file from after they are deleted, they come back within 1 min of deletion..

    Any help would be great.
