The JSP engine does not process any of the remainder of the JSP file.</p><p><a name="17086"> </a>If the output from the compiled JSP file is buffered (by using a <code>page</code> directive with the default value or an explicit size set for <code>buffer</code>), the buffer is cleared before the request is forwarded. If the output is not buffered (if you used a page directive with <code>buffer=none</code>), and if anything has been written to the buffer, using <code><jsp:forward></code> results in an <code>IllegalStateException</code>.</p><a name="15703"> </a><h4> Attributes</h4><ul><a name="15704"> </a><li><code>page="{ </code><em>relativeURL</em><code> | <%= </code><em>expression</em><code> %> }"</code><p><a name="15705"> </a>A <code>String</code> or an expression representing the relative URL of the file to which you are forwarding the request.</p><p><a name="17094"> </a>The relative URL looks like a path-it cannot contain a protocol name, port number, or domain name. The URL can be absolute or relative to the current JSP file. If it is absolute (beginning with a /), the path is resolved by your Web or application server. </p></ul><a name="15708"> </a><h4> See Also</h4><ul><a name="15712"> </a><li><a href="syntaxref.fm6.html#8772">Include Directive</a><a name="15716"> </a><li><code><a href="syntaxref.fm11.html#8828"><jsp:include></a></code><a name="15720"> </a><li><a href="syntaxref.fm7.html#15653">Page Directive</a></ul><hr><br> <a href="tags.html">[Top]</a> <a href="syntaxref.fm8.html">[Prev]</a> <a href="syntaxref.fm10.html">[Next]</a> <a href="Copyright.fm.html">[Bottom]</a><hr><br><i>Copyright © 1999, Sun Microsystems, Inc.
