By default, AOPS2 sends a cachebuster query with every patch file to download. This ensures it doesn’t use any server cached copy of the file and uses the direct file from the server. If you are using one of our patch servers, it is ok to use None as the files are only cached until new files are updated. However, if you are using your own hosting, some files may still retain a cached copy on the server not reflecting the new file.
You can select from two options for cachebusting. Default sends a cachebuster query with every download. None tells AOPS2 not to use any cachebusting.
