caching images served by servlet

Question

I\'m serving up images from my servlet. The response content type is image/jpeg. I find that images requested from my servlet are not cached. How do I get them to be cached

Answer 1

Ok.. looks like the default header fields should enable caching. I found a solution in another forum. Apparently, you need to explicitly set a content-length in the response. Wonder why though. I thought the HttpServletResponse would do that for us. Anyway, it worked like a charm and the image is getting cached nicely.
