The matrix

A quick overview of the matrix:

• The matrix is made of cells.
  • Each cell is bound to a hostname, a type of request, or both.
• A greenish cell (pale or dark) represents a request to allow.
  • Dark green means there is an explicit whitelist rule assigned to the cell.
  • Pale green means the whitelist status is inherited from another higher precedence cell in the matrix.
• A reddish cell (pale or dark) represents a request to block.
  • Dark red means there is an explicit blacklist rule assigned to the cell.
  • Pale red means the blacklist status is inherited from another higher precedence cell in the matrix.
• A pale green or pale red cell is also referred to as being graylisted.
  • A graylisted cell always inherit its whitelist or blacklist status from an higher precedence cell.
• The top row lets you control the types of request which are to be allowed/denied.
• The left-most column lets you control the hostnames which are to be allowed/denied.
• The top-left cell lets you control all the other cells in the matrix.
  • A click on that single cell allows you to whitelist or blacklist all the cells in the matrix -- except those cells which are explicitly white or blacklisted.
  • This cell affects the status of graylisted cells in the top row and the left-most column.
  • In turn, the cells in the top row affect the status of graylisted cells under them.
  • In turn, the cells in the left-most column affect the status of graylisted cells on their right.
