Headers

The Headers class manages headers sent to the browser

There are 2 different methods to set headers:

  • The status headers are sent via setResponseStatus()
  • Rest of headers are sent via set() method

The headers are stacked and are not sent to the browser until the controller has finished the execution and right before the echo of the content. If you need to write the headers right away you can force the \Sifo\Headers::send() anytime.

Example of usage:

\Sifo\Headers::set( 'Content-Type', 'application/json' );
\Sifo\Headers::set( 'Cache-Control', 'public, must-revalidate, max-age=0, s-maxage=30' );

All the activity with headers is logged and shown in the Debug:
