WinRoute provides a wide range of features to filter traffic using HTTP and FTP protocols. These protocols are the most spread and the most used in the Internet.

Here are the main purposes of HTTP and FTP content filtering:

Let's focus on filtering options featured by WinRoute. For their detailed description, read the following chapters.

HTTP protocol

— Web pages filtering:

  • access limitations according to URL (substrings contained in URL addresses)

  • blocking of certain HTML items (i.e. scripts, ActiveX objects, etc.)

  • filtering based on classification by the ISS OrangeWeb Filter module (worldwide Website classification database)

  • limitations based on occurrence of denied words (strings)

  • antivirus control of downloaded objects

FTP protocol

— control of access to FTP servers:

  • access to certain FTP servers is denied

  • limitations based on or file names

  • transfer of files is limited to one direction only (i.e. download only)

  • certain FTP commands are blocked

  • antivirus control of transferred files

Note: WinRoute provides only tools for filtering and access limitations. Decisions on which websites and files will be blocked must be made by the administrator (or another qualified person).
