Hello,
we noticed that HTTP 302 responses from wayback are cached, which is contradicts the
HTTP protocol 2616:
10.3.3 302 Found
The requested resource resides temporarily under a different URI.
Since the redirection might be altered on occasion, the client SHOULD
continue to use the Request-URI for future requests. This response
is only cacheable if indicated by a Cache-Control or Expires header
field.
perhaps there is a response from the IA server to squid that allows the caching and we're not seeing it?
As you can see from example below, the timegate responses (302s) are *too* cachable.
