non-blocking image generation over http

[Drew Kutcharian]

Hi All,

I'm trying to implement a simple web service that generate images using Netty. I'm using the Netty's HttpStaticFileServer example as a base. The issue is the image generation is a slow process and I don't want to block when the image is being generated. 

I see that in the example most of the work is being done in HttpStaticFileServerHandler.messageReceived(). Is that where I should put the image generation code?

BTW, where can I find a bit more about the Netty Thread model? I would like to know how the methods are being called from various (boss/worker) threads.

Thanks,

Drew
