<span class="function"><strong>nsapi_virtual()</strong></span> is an NSAPI-specific function which
is equivalent to <em><!--#include virtual...--></em>
in <acronym>SSI</acronym>
(<var class="filename">.shtml</var> files). It does an NSAPI sub-request.
It is useful for including CGI scripts or .shtml files, or anything
else that you'd parse through webserver.
</p>
<p class="para">
To run the sub-request, all buffers are terminated and flushed to the
browser, pending headers are sent too.
</p>
<p class="para">
You cannot make recursive requests with this function to other PHP scripts.
If you want to include PHP scripts, use <span class="function"><a href="function.include.html" class="function">include</a></span> or
<span class="function"><a href="function.require.html" class="function">require</a></span>.
</p>
<blockquote class="note"><p><strong class="note">Note</strong>:
<p class="para">
This function depends on a undocumented feature of the Netscape/iPlanet/Sun
webservers. Use <span class="function"><a href="function.phpinfo.html" class="function">phpinfo()</a></span> to determine if it is available.
In the Unix environment it should always work, in Windows it depends on the name of
a <var class="filename">ns-httpdXX.dll</var> file.
</p>
<p class="para">
Read the note about subrequests in the NSAPI section (<a href="install.unix.sun.html#install.unix.sun.notes" class="link">UNIX</a>, <a href="install.windows.sun.html#install.windows.sun.notes" class="link">Windows</a>) if you experience
this problem.
