This server allows viewing of attachments in online Zotero libraries. There are two types of attachments supported:

• Single files (e.g., PDFs): Streamed directly from S3.
• Zipped webpage snapshots: Downloaded from S3 and mounted while user is loading the webpage snapshot. After a while the ZIP file is unmounted and deleted.
