WebCookiesSniffer is a packet sniffer tool that captures all Web site cookies sent between the Web browser and the Web server and displays them in a simple cookies table. The upper pane of WebCookiesSniffer displays the cookie string and the Web site/host name that sent or received this cookie. When selecting a cookie string in the upper pane, WebCookiesSniffer parses the cookie string and displays the cookies as name-value format in the lower pane.

System Requirements

• This utility works on any version of Windows, starting from Windows 2000 and up to Windows 7, including 64-bit systems.
• One of the following capture drivers is required to use WebCookiesSniffer:
  • WinPcap Capture Driver: WinPcap is an open source capture driver that allows you to capture network packets on any version of Windows. You can download and install the WinPcap driver from this Web page.
  • Microsoft Network Monitor Driver version 2.x (Only for Windows 2000/XP/2003): Microsoft provides a free capture driver under Windows 2000/XP/2003 that can be used by WebCookiesSniffer, but this driver is not installed by default, and you have to manually install it, by using one of the following options:
    • Option 1: Install it from the CD-ROM of Windows 2000/XP according to the instructions in Microsoft Web site
    • Option 2 (XP Only) : Download and install the Windows XP Service Pack 2 Support Tools. One of the tools in this package is netcap.exe. When you run this tool in the first time, the Network Monitor Driver will automatically be installed on your system.
  • Microsoft Network Monitor Driver version 3.x: Microsoft provides a new version of Microsoft Network Monitor driver (3.x) that is also supported under Windows 7/Vista/2008.
    The new version of Microsoft Network Monitor (3.x) is available to download from Microsoft Web site.
• You can also try to use WebCookiesSniffer without installing any driver, by using the ‘Raw Sackets’ method. Unfortunately, Raw Sackets method has many problems:
  • It doesn’t work in all Windows systems, depending on Windows version, service pack, and the updates installed on your system.
  • On Windows 7 with UAC turned on, ‘Raw Sackets’ method only works when you run WebCookiesSniffer with ‘Run As Administrator’.
