4.3.1 Table Object (mp_table)<a name='l2h-20'> </a>
</H2>
<P>
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.
<P>
Much of the information that Apache uses is stored in tables. For
example, <tt class="member">Request.header_in</tt> and <tt class="member">Request.headers_out</tt>.
<P>
All the tables that mod_python provides inside the <tt class="class">Request</tt>
object are actual mappings to the Apache structures, so changing the
Python table also changes the underlying Apache table.
<P>
In addition to normal dictionary-like behavior, the table object also
has the following method:
<P>
<dl><dt><b><a name='l2h-21'><tt class='method'>add</tt></a></b>(<var>key, val</var>)
<dd>
<tt class="function">add()</tt> allows for creating duplicate keys, which is useful
when multiple headers, such as <code>Set-Cookie:</code> are required.
</dl>
