Configuring multiple caching proxies
You can configure multiple caching proxies by suffixing the 'CACHE' part of configuration variables with a number, i.e.
CACHE_BACKEND
Caching backends include a protocol, domain/ip and an optional port. Although the protocol may be https, this is not advised since the proxy is not optimized to handle https connections to backends 'far away', and for SNI.
If you need https connections to remote backends, you can put a forward proxy in between (like the FlowForward proxy of this series).
CACHE_STRATEGY
Cache strategies knows to possible values, 'force' and 'obey' (default).
If the strategy is 'force', all content is cached regardless of the cache headers sent by the backend. Additionally, the caching TTL is the TTL as configured by CACHE_TTL or DEFAULT_TTL.
If the strategy is 'obey', the caching proxy will listen to headers sent by the backend (like Cache-Control).
