问题
I have already asked about this for android, but I will broaden the question to include java in general... Are there any libraries for implementing a Http cache? I want to download my images more efficiently, honoring If-Modified-Since, etags, etc.
I'm sure there is a library to which one can pass the url of the image and let the lib handle all redirects or fetch the locally stored content in a cache?
