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). <P> <div class="seealso"> <p class="heading"><b>See Also:</b></p> <dl compact class="seeurl"> <dt><a href="http://dev.apache.org/" class="url">http://dev.apache.org/</a> <dd>Apache Developer Resources </dl> <dl compact class="seeurl"> <dt><a href="http://www.modpython.org/python10/" class="url">http://www.modpython.org/python10/</a> <dd>Mod_Python - Integrating Python with Apache, presented at Python 10 </dl> </div> <P> <DIV CLASS="navigation"> <p><hr> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td><A href="intr-performance.html"><img src="icons/previous.png" border="0" height="32" alt="Previous Page" width="32"></A></td> <td><A href="introduction.html"><img src="icons/up.png" border="0" height="32" alt="Up One Level" width="32"></A></td> <td><A href="intr-history.html"><img src="icons/next.png" border="0" height="32" alt="Next Page" width="32"></A></td> <td align="center" width="100%">Mod_python Manual</td> <td><A href="contents.html"><img src="icons/contents.png" border="0" height="32" alt="Contents" width="32"></A></td> <td><img src="icons/blank.png" border="0" height="32" alt="" width="32"></td> <td><A href="genindex.html"><img src="icons/index.png" border="0" height="32" alt="Index" width="32"></A></td> </tr></table> <b class="navlabel">Previous:</b> <a class="sectref" href="intr-performance.html">1.1 Performance</A> <b class="navlabel">Up:</b> <a class="sectref" href="introduction.html">1.
