As Designed Image Proxy doesn't respect cache headers

    Images shouldn't be cached for longer than the Cache-Control header specifies.

    While I appreciate the sentiment, this is really the designed behavior for the image proxy. It's not designed to be a simple client-side cache and disabling caching (for example) could very easily lead to a degraded experience (slow servers) and potentially a significant bandwidth increase.

    The problem I have is that many users (especially in their signatures) have dynamic images that change on a frequent basis, yet the image proxy is needed for full https integration.
    Maybe the cache time could be set:
    cacheTime = (cacheHeader minCache) ? minCache : ((cacheHeader maxCache)? cacheHeader maxCache);
    That way everything gets cache for at least some period, and those which need to be refreshed frequently can be.

    News in what sense?

    As the prefix denotes, this is as designed.
