Development Planning

• Caching With Squid

  • Zope communicates with Squid via HTTP headers in the response.
  • Cache headers that are relevant:
    • Date: <date>
    • Expires: <date>
    • Pragma: <no-cache> (HTTP 1.0)
    • Cache-control: <no-cache> <max-age> <public> <private> <must-revalidate> (HTTP 1.1)
  • Accelerated HTTP Cache Manager and CMF Caching Policy Manager set these headers, but you can set them manually too.
