# Feature: #82419 - Send Frontend Debug Information as HTTP Response Header

See [forge#82419](https://forge.typo3.org/issues/82419)

## Description

When setting `config.debug=1` or `$TYPO3_CONF_VARS[FE][debug]` the parse time is now sent as HTTP
response header "X-TYPO3-Parsetime" instead of HTML comments.

## Impact

This ensures that non-HTML-content (e.g. JSON output) does not break when having debugging for the
Frontend enabled.

If you look for the parse time of a frontend request, this can now easily be shown via
`curl -I https://mydomain.com` or in the developer toolbar of the browser.
