The module gets compiled as a shared library which is dynamically loaded by the server at run time. <P> The advantage of DSO is that a module can be installed without recompiling Apache and used as needed. A more detailed description of the Apache DSO mechanism is available at <a class="url" href="http://httpd.apache.org/docs-2.0/dso.html">http://httpd.apache.org/docs-2.0/dso.html</a>. <P> <em>At this time only DSO is supported by mod_python.</em> <P> <i class="dfn">Static</i> linking is an older approach. With dynamic linking available on most platforms it is used less and less. The main drawback is that it entails recompiling Apache, which in many instances is not a favorable option. <P> <p><br /></p><hr class='online-navigation' /> <div class='online-navigation'> <!--Table of Child-Links--> <A NAME="CHILD_LINKS"><STRONG>Subsections</STRONG></a> <UL CLASS="ChildLinks"> <LI><A href="inst-configure.html">2.2.1 Running ./configure</a> <LI><A href="inst-make.html">2.2.2 Running make</a> </ul> <!--End of Table of Child-Links--> </div> <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="2.1 Prerequisites" href="inst-prerequisites.html"><img src='previous.png' border='0' height='32' alt='Previous Page' width='32' /></A></td> <td class='online-navigation'><a rel="parent" title="2.
