This demo will allow you to convert any URL to a MHT document. Once you enter
your url, and click "Convert to MHT", aspNetMHT will fetch the Url’s contents,
convert them to a MHT, compress to a zip archive, and allow you to download.
Please note, that urls will be cached for 1 day. For example, if you select
www.yahoo.com, and someone else also selected www.yahoo.com a few hours ago,
you will see the cached version.
