I wanted to note as an aside that this is precisely the kind of issue that  
PEP 'scope' addresses. Rather than per-header table lookups that imply  
properties-about-orignal-resource, properties-about-resource-as-caches,  
properties-about-immediate-connection, and properties-about-origin-services,  
PEP scope and strength tagging allows proxies to reason exactly about  
disposing of unknown features.

See Section 3.4 and Appendix A.3 for more details:
