was relatively easy to capture the original content that the user was
downloading. Ie. in the original DNS request the URL information would be
included in the packet info. Are people using DNS logs to capture this
type of URL traffic? If so, does it provide the full URL, or just the DNS
host name? DNS host name would be useful, but full URL would be even
