Is it possible to cache a list of website urls, image urls etc without opening them first in a webview? I have a list of img urls coming from a feed that i want to cache on download. i have already posted a question about this but have gotten no response here is my previous question.

It's not possible to drop things into the WebView's cache directly. The only way that would not require preloading in an "off-screen" WebView (which is totally possible, btw.) would be to download the images yourself and serve them back to the WebView using shouldInterceptRequest.
I would recommend caution with the shouldInterceptRequest-based approach though. It's easy to hurt performance when using shouldInterceptRequest (see here). Also, you need to take care of removing stale images from your 'cache'.
