var url = document.URL;
var page_start = url.indexOf("page=");
var page_end = url.length;
if ((page_start > 0) && ((page_start + 5) < page_end)) {
var page = url.substring(page_start + 5, page_end);
};
var makefs = true;
if (page.indexOf('://') >= 0) {
if (page.indexOf(window.location.protocol + '//' + document.domain + '/') != 0) {
makefs = false;
document.location.pathname = '/';
};
};
if (makefs) {
var ULT_LINK = new Array(); // Usado para volver a portada.
page = page + '?' + Math.random();
document.write('<frameset rows="35,1*" frameborder="NO" border="0" framespacing="0"> ');
document.write('<frame name="head" noresize scrolling="NO" src="/fset/head.html" marginwidth="0" marginheight="0" frameborder="NO">');
document.write('<frameset rows="*" cols="1,1*" frameborder="NO" border="0" framespacing="0"> ');
document.write('<frame name="cont1" scrolling="NO" noresize marginwidth="0" marginheight="0" frameborder="NO">');
document.write('<frameset rows="*" cols="140,1*" frameborder="NO" border="0" framespacing="0"> ');
document.write(' <frame name="menu" noresize scrolling="NO" src="/p4_extension/site/port/menu.html" marginwidth="0" marginheight="0" frameborder="NO">');
document.write(' <frame name="cont2" src="' + page + '" marginwidth="0" marginheight="0" frameborder="NO">');
document.write('</frameset>');
