When connecting to a site through a webApp, like Microsoft SharePoint server, through stoneware, ie shows the message "Security Information alert : The page contains both secure and nonsecure items"
This comes from IE seeing requests for HTTP and HTTPS connections in the same page. This is to alert you that not all of the data will be secure.
To fix it, use a program like IEWatch ( www.iewatch.com ) for IE or the Tamper Data plugin for Firefox to view the data stream and determine what page or graphic is being loaded with HTTP:// instead of HTTPS:// Then fix the actual page if you have access to the server, typically the publisher of that page has used an absolute URL instead of a relative one and it does not handle being SSL'd.
The second option is to use a stoneware rule and assign that to the webApp. The rule can search for a HTML tag and attribute, and replace the HTTP with HTTPS. If you have many of them, you can use * for tag and * for attribute to catch all cases.
