[Freeswitch-users] http_cache use of local cache directory

Hello. I'm trying to figure out how mod_htp_cache uses the local cache directory when uploading a file to S3. Speciffically I would like to know how long will the file be kept in the local file system cache (by default /usr/local/freeswitch/cache) in the case of an error while uploading to S3. Will it be deleted next time freeswitch starts? Will it stay there forever? The reason I'm asking is because we are trying to implement a fallback system to recover and upload recordings to S3 in case there was a problem when http_cache first attempted to upload the file (for example a 403 error, or a connectivity issue). Thanks a lot for your help. Francisco Caraballo
