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.
