<h1>How it works</h1>
|
||||
<p> Each time the server detects a tag of the form <code><!--#name--></code> in a .shtml, .ssi or .shtm file
|
||||
where <code>name</code> appears as one of the tags supplied to <code>http_set_ssi_handler</code> in the <code>pcConfigSSITags</code> array,
|
||||
an insert string is appended after the tag string in file and sent back to the client.</p>
|
||||
<p>A CGI handler function is called each time the server is asked for a file
|
||||
whose name was previously registered as a CGI function using a call to <code>http_set_cgi_handler</code>.
|
||||
This function allows you to access the parameters provided along with the URI.</p>
