popURL is a small Windows tool that displays useful information from an HTTP URL, such as the remote server´s software and the particulars of the file to be fetched. This data can be useful in a diagnostic or security context.

To use, simply copy an HTTP URL to the clipboard (e.g. ´Copy Link Location´ in your web browser) and then left-click the ´U´ icon in the tray. A popup will appear, showing you various information about the URL.

• Site name: The base site in the URL. Click the ´S´ button on the right to automatically launch your web browser and visit the base site URL.
• Web server: The server´s software, for example IIS or Apache. Sites on some platforms, such as Microsoft IIS, may pose more of a risk than others. Click the ´W´ button to launch a Google search for the server type.
• MIME type: The MIME Content-Type for the file, as reported by the web server. This identifies whether a URL is text, multimedia, etc. Click the ´M´ button to launch a Google search for the given media type.
• File size: The MIME Content-Length for the file. This field is often not present for dynamically generated content. popURL will also display the size in kilobytes (2^10) and megabytes (2^20).

The complete server response is also displayed in the scrolling window near the top of the popup. NOTE THAT SERVER RESPONSES MAY INCLUDE FORGED DATA.
