hmm, I don’t know if you have changed the default proxy.config.http.cache.required_headers from 2 to 1 or 0. if you don’t change it, your content is not save-able.
FYI: # required headers: three options: # 0 - No required headers to make document cachable # 1 - "Last-Modified:", "Expires:", or "Cache-Control: max-age" required # 2 - explicit lifetime required, "Expires:" or "Cache-Control: max-age" CONFIG proxy.config.http.cache.required_headers INT 2 according to your response headers, there is only Last-Modified header there.
