HTTPNetworkSniffer v1.50 - Packet Sniffer Tool That Captures All HTTP Requests/Responses

Thursday, November 19, 2015


HTTPNetworkSniffer is a packet sniffer tool that captures all HTTP requests/responses sent between the Web browser and the Web server and displays them in a simple table. For every HTTP request, the following information is displayed: Host Name, HTTP method (GET, POST, HEAD), URL Path, User Agent, Response Code, Response String, Content Type, Referer, Content Encoding, Transfer Encoding, Server Name, Content Length, Cookie String, and more...

You can easily select one or more HTTP information lines, and then export them to text/html/xml/csv file or copy them to the clipboard and then paste them into Excel.

System Requirements
  • This utility works on any version of Windows, starting from Windows 2000 and up to Windows 10, including 64-bit systems.
  • One of the following capture drivers is required to use HTTPNetworkSniffer:
    • 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 HTTPNetworkSniffer, but this driver is not installed by default, and you have to manually install it, by using one of the following options:
    • 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 HTTPNetworkSniffer without installing any driver, by using the 'Raw Sockets' method. Unfortunately, Raw Sockets 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 Sockets' method only works when you run HTTPNetworkSniffer with 'Run As Administrator'. 

Start Using HTTPNetworkSniffer

Except of a capture driver needed for capturing network packets, HTTPNetworkSniffer doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - HTTPNetworkSniffer.exe

After running HTTPNetworkSniffer in the first time, the 'Capture Options' window appears on the screen, and you're requested to choose the capture method and the desired network adapter. In the next time that you use HTTPNetworkSniffer, it'll automatically start capturing packets with the capture method and the network adapter that you previously selected. You can always change the 'Capture Options' again by pressing F9.

After choosing the capture method and network adapter, HTTPNetworkSniffer captures and displays every HTTP request/response sent between your Web browser and the remote Web server.

Command-Line Options

/load_file_pcap <Filename> Loads the specified capture file, created by WinPcap driver.
