Methods

Sanitize(IDictionary<string, object?>?, IEnumerable<string>?, IEnumerable<string>?)

Sanitizes a dictionary of headers by:

1. Replacing the value of any key in the built‑in set of sensitive headers set with "[REDACTED]".
2. Removing carriage return, line feed, and null characters from all header values.
3. Optionally restricting headers to a pre‑defined set of allowed keys.

The original dictionary is not modified.

Declaration

public static IDictionary<string, object?> Sanitize(IDictionary<string, object?>? headers, IEnumerable<string>? additionalSensitiveKeys = null, IEnumerable<string>? allowedKeys = null)

Parameters

Type	Name	Description
IDictionary<string, object>	headers	The headers to sanitize. Can be null.
IEnumerable<string>	additionalSensitiveKeys	Additional sensitive keys to redact (on top of the built‑in set).
IEnumerable<string>	allowedKeys	If provided, only headers whose keys are in this set will be included in the result. If null or empty, all non‑redacted headers are kept.

Returns

Type	Description
IDictionary<string, object>	A new, safe dictionary. Never returns null.
