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">See Also:</p> <dl compact="compact" class="seeurl"> <dt><a href="http://dev.apache.org/" class="url">http://dev.apache.org/</a></dt> <dd>Apache Developer Resources</dd> </dl> <dl compact="compact" class="seeurl"> <dt><a href="http://www.modpython.org/python10/" class="url">http://www.modpython.org/python10/</a></dt> <dd>Mod_Python - Integrating Python with Apache, presented at Python 10</dd> </dl> </div> <P> <DIV CLASS="navigation"> <div class='online-navigation'> <p></p><hr /> <table align="center" width="100%" cellpadding="0" cellspacing="2"> <tr> <td class='online-navigation'><a rel="prev" title="1.1 Performance" href="intr-performance.html"><img src='previous.png' border='0' height='32' alt='Previous Page' width='32' /></A></td> <td class='online-navigation'><a rel="parent" title="1.
