1.2 Flexibility
</H1>
<P>
Apache processes requests in phases (e.g. read the request, parse
headers, check access, etc.). These phases can be implemented by
functions called handlers. Traditionally, handlers are written in C
and compiled into Apache modules. Mod_python provides a way to
extend Apache functionality by writing Apache handlers in
Python. For a detailed description of the Apache request processing
process, see the <em class="citetitle"><a
href="http://dev.apache.org/API.html"
title="Apache
API Notes"
>Apache
API Notes</a></em>, as well as the
<em class="citetitle"><a
href="http://www.modpython.org/python10/"
title="Mod_python -
Integrating Python with Apache"
>Mod_python -
Integrating Python with Apache</a></em> paper.
<P>
To ease migration from CGI, a standard mod_python handler is
provided that simulates the CGI environment allowing a user to run
legacy scripts under mod_python with no changes to the code (in most
cases).
