&lt;h1&gt;Script Handler&lt;/h1&gt;&lt;section class=&quot;ls-spacer-small-bottom&quot;&gt;LiteSpeed Web Server supports all scripting languages including 
Perl, PHP, Ruby, Python, Java, etc. Scripts written in these different 
languages must be brought to the appropriate external application to be processed. 
LiteSpeed Web Server uses script handlers to decide which external application a 
script should go to. These script handlers map files to external applications by 
using the file suffix. (Actually, the suffix is used to determine a MIME 
type which is then mapped to the external application.) External applications 
must be set up in the External Application tab before they can be selected for 
use in a script handler.
&lt;br /&gt;&lt;br /&gt;
You can set up script handler at the server or virtual host level. Server-level
script handlers apply to all virtual hosts unless overridden in virtual host level. 
Virtual host-level script handlers only apply within that virtual host.&lt;/section&gt;
&lt;h2 id=&quot;top&quot;&gt;Table of Contents&lt;/h2&gt;&lt;section class=&quot;toc&quot;&gt;&lt;section class=&quot;toc-row&quot;&gt;&lt;header&gt;Script Handler Definition&lt;/header&gt;&lt;p&gt;
&lt;a href=&quot;#suffix&quot;&gt;Suffix&lt;/a&gt; | &lt;a href=&quot;#shType&quot;&gt;Handler Type&lt;/a&gt; | &lt;a href=&quot;#shHandlerName&quot;&gt;Handler Name&lt;/a&gt;&lt;/p&gt;&lt;/section&gt;
&lt;/section&gt;
&lt;section&gt;&lt;div class=&quot;helpitem&quot;&gt;&lt;article class=&quot;ls-helpitem&quot;&gt;&lt;div&gt;&lt;header id=&quot;suffix&quot;&gt;&lt;h3&gt;Suffix&lt;span class=&quot;ls-permlink&quot;&gt;&lt;a href=&quot;#suffix&quot;&gt;&lt;/a&gt;&lt;/span&gt;&lt;span class=&quot;top&quot;&gt;&lt;a href=&quot;#top&quot;&gt;&amp;#8657;&lt;/a&gt;&lt;/span&gt;&lt;/h3&gt;&lt;/header&gt;&lt;/div&gt;&lt;h4&gt;Description&lt;/h4&gt;&lt;p&gt;Specifies the script file suffixes that will be handled by this  script handler. Suffixes must be unique.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;Comma delimited list with period &quot;.&quot; character prohibited.&lt;/p&gt; &lt;h4&gt;Tips&lt;/h4&gt;&lt;p&gt;&lt;span title=&quot;Information&quot; class=&quot;ls-icon-info&quot;&gt;&lt;/span&gt; The server will automatically add a special MIME type (&quot;application/x-httpd-[suffix]&quot;) for the first  suffix in the list. For example, MIME type &quot;application/x-httpd-php53&quot; will be added  for suffix &quot;php53&quot;. Suffixes after the first need to set up in the &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;#mime&quot;&gt;MIME Settings&lt;/a&gt;&lt;/span&gt; settings.&lt;br/&gt; Though we list suffixes in this field, the script handlers use MIME types, not suffixes,  to decide which scripts to handle. You can thus use the Apache configuration directives  &quot;AddType&quot; and &quot;ForceType&quot; (which control file MIME types) in .htaccess files to change  which script handler certain files will use. For example, with the directive  &lt;span class=&quot;cmd&quot;&gt; AddType application/x-httpd-php53 .php&lt;/span&gt; in a properly placed .htaccess file,  you can stipulate that php files in this directory have the MIME type &quot;application/x-httpd-php53&quot; and  thus will be handled by the script handler that uses MIME type &quot;application/x-httpd-php53&quot;  (suffix &quot;php53&quot;). This then allows you to assign different script handlers, not only for  different file suffixes, but also based on the locations of files.&lt;br/&gt; &lt;span title=&quot;Performance&quot; class=&quot;ls-icon-performance&quot;&gt;&lt;/span&gt;&lt;span title=&quot;Security&quot; class=&quot;ls-icon-security&quot;&gt;&lt;/span&gt; Only specify the suffixes you really need.&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;
&lt;div class=&quot;helpitem&quot;&gt;&lt;article class=&quot;ls-helpitem&quot;&gt;&lt;div&gt;&lt;header id=&quot;shType&quot;&gt;&lt;h3&gt;Handler Type&lt;span class=&quot;ls-permlink&quot;&gt;&lt;a href=&quot;#shType&quot;&gt;&lt;/a&gt;&lt;/span&gt;&lt;span class=&quot;top&quot;&gt;&lt;a href=&quot;#top&quot;&gt;&amp;#8657;&lt;/a&gt;&lt;/span&gt;&lt;/h3&gt;&lt;/header&gt;&lt;/div&gt;&lt;h4&gt;Description&lt;/h4&gt;&lt;p&gt;Specifies the type of external application that processes these script files.   Available types are: &lt;span class=&quot;val&quot;&gt;CGI&lt;/span&gt;, &lt;span class=&quot;val&quot;&gt;FastCGI&lt;/span&gt;, &lt;span class=&quot;val&quot;&gt;Web Server&lt;/span&gt;, &lt;span class=&quot;val&quot;&gt;LSAPI app&lt;/span&gt;, &lt;span class=&quot;val&quot;&gt;Load balancer&lt;/span&gt;, or &lt;span class=&quot;val&quot;&gt;Servlet Engine&lt;/span&gt;.  For FastCGI, Web Server and Servlet Engine, a &lt;span class=&quot;tagl&quot;&gt;&lt;a href=&quot;#shHandlerName&quot;&gt;Handler Name&lt;/a&gt;&lt;/span&gt; needs to be specified.  This is an external application name as predefined in the &lt;span class=&quot;tagP&quot;&gt;&lt;a href=&quot;#ExtApp_Help&quot;&gt;External Apps&lt;/a&gt;&lt;/span&gt; section.&lt;/p&gt; &lt;h4&gt;Syntax&lt;/h4&gt;&lt;p&gt;Select from drop down list&lt;/p&gt; &lt;/article&gt; &lt;/div&gt;
