Thanks Alex. I had a peek at your blog and followed the link for localhost but they say it doesn't work at for the local ip address of 127.0.0.1 - on Windows. All the same, thank you for telling me about it, it sounds really good. I shall give it a go for other purposes. I wonder if Charles will capture localhost traffic?
