Cache-Keys and multiple blogs


Since I'm using the SQLBlogProvider and multiple blogs the twitter widget seems to get crosslinked between several sites that have different configurations saved. What I mean is that one Blog may display the Tweets from another Blog's Twitter widget settings. If this is a bug, I may be able to find it, but I assume that this was intended for a single Blog only. If this is the case, would that change how I would cache, or can I just turn off the cache altogether? Any other thoughts on this and/or have you seen this before?
I am looking for the code solution. There's no assumption it's a simple checkbox item in the UI.
