@Bugger: I guess that dialog window appears when you do a right click on a incoming connection, and choose 'View http request', isn't it? (I mean, that window doesn't show up automatically). In that case, that connection could be related to a response from the server to a banned user (I'm just guessing, not sure about it). If you share more details (at least, privately with Rejetto), I'm sure he could give you a more appropriate answer to this. It would be nice to know if you are using the default template, and if you have any 'ban' rule. To help you, we need more details on how and when that window appears...
