Where 500 KB matters

A 512,000-byte file: larger than most API body limits, smaller than most upload limits. These are the default limits a file of this size is useful for testing:

System	Limit	Note
Amazon DynamoDB items	400 KB per item	500 KB cannot be stored as a single item.
Express body parsers	100 KB by default	Rejected unless the limit is raised.
nginx request body	1 MB by default (client_max_body_size)	Accepted with room to spare.

All 500 KB sample files

Use this file for

Testing that APIs return 413 for oversized bodies
Testing XML parsers and data import
Checking protection against entity attacks

Testing notes for XML

Parsers that resolve external entities can be made to read local files or call internal services, an attack called XXE. Disable DTD processing for untrusted input.
Nested entity definitions can expand exponentially ("billion laughs"). The samples here declare no entities.
