The Download process

The first thing the script client does is validate that the specified job exists for this particular organisation. If the job is located, the packing slip is downloaded and saved in the log directory. The packing slip contains the names of all the files to download and the rules to apply while downloading.

For each file, it checks if the file already exists in the download directory. If the file already exists and overwrite is set to false, then this file is not downloaded and an error is written to the logs. If overwrite is permitted, then the last modified date of the file is checked to make sure it has exceeded the overwriteAfter period. If the modification date of the file is later than the overwriteAfter period, the file is downloaded and over writes the existing file. Otherwise, the file will not be downloaded and an error will be recorded in the logs.

The overwrite and overwriteAfter values are specified in the Job maintenance window for this particular job. Note the overwriteAfter period is in milliseconds.
