This block is part of the http connection group and was last modified in core v10.4.28.

single header value v10.4.28

Gets the given header if present in HTTP request.

In pins 2

connection required
httpconnection
name required
value

Out pins 1

value
value

Outputs the value of a single request header; the name pin is lowercased before lookup, so casing never matters. Emits nil when the header is absent, the name is empty, or the connection is unwired.

A typical wiring for single header: value feeds the name pin; the value out pin feeds convert to uppercase.

Version history

Introduced in v10.4.28.
