4.3.1 Table Object (mp_table)

The table object is a Python mapping to the Apache table. The table object performs just like a dictionary, with the only difference that key lookups are case insensitive.

Much of the information that Apache uses is stored in tables. For example, `Request.header_in` and `Request.headers_out`.

All the tables that mod_python provides inside the `Request` object are actual mappings to the Apache structures, so changing the Python table also changes the underlying Apache table.

In addition to normal dictionary-like behavior, the table object also has the following method:

`add`(key, val)
  `add()` allows for creating duplicate keys, which is useful when multiple headers, such as `Set-Cookie:` are required.
