# single header

This block is part of the [`http connection`](https://docs.rual.nl/block-types/http%20connection) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Gets the given header if present in HTTP request.

- connection required `httpconnection`

- name required `value`

- value `value`

A typical wiring for [single header](https://docs.rual.nl/block-types/http%20connection/httpconnection_get_header): [value](https://docs.rual.nl/block-types/value/value_default) feeds the `name` pin; the `value` out pin feeds [convert to uppercase](https://docs.rual.nl/block-types/value/value_to_uppercase).
