Caching Issues
- Authentication and personalization: don't show Jim's rendering of content to Fred. Cache servers only pay attention to headers and URLs, not content. Essentially, you cannot serve up a single “canonical” cached page for a personalized resource.
- Use “Vary” tags to cache various versions of personalized pages. CMF Caching Policy manager allows for this.
- Personalization and authentication is expensive. If you can avoid it, try. If you can't, try to use client-side facilities to do personalization. If you can't do that, try using ESI or similar.
