The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Ajax request to another server - Access Denied

Asked by MMDeveloper in Asynchronous Javascript and XML (AJAX), JavaScript, PHP and Databases

Tags: , ,

Is there any way around this issue? At work we are using this terrible software solution called zWeb/Host. It has no support for server-side scripting so just for speed reasons, I host all images/css/javascript/etc on a (separate) virtual server within the same network. The graphics/css/javascript are loaded fine; however any ajax request to a server-side script (a php session handler in this case), produces a security error alert.

IE of course permits it to happen (no surprise there....) however the good browsers wont permit it due to a security error.

The exact error message is:

Security Error: Content at file:///C:/Documents%20and%20Settings/fordm/Desktop/_dev/dev.html may not load data from http://nric-20896/zWebHost/phpZwebHelpers/sessionHandler.php.

I know this is probably considered cross-site-scripting and violates the "Same Origin Policy" but I was wondering if there was a work-around. I'm using the Ajax library from prototype-js.orgStart Free Trial

JS:

PHP Session Handler:
 
<?php
session_start();
 
	/*
		By:	Matt F.
 
		Purpose:	This is a session handler for zWebHost. It currently is not serving
				any function, but is in place in the event extra session handling
				functionality is needed. This script is hit via an Ajax routine,
				once per page, on page load.
	*/
 
 
class sessionHandler {
 
	var $request = NULL;
	var $session = NULL;
 
	function __construct($data) {
		$this->sessionHandler($data);
	}
 
	function sessionHandler($data) {
		$this->request = $data;
		$this->session = $_SESSION;
 
		$this->processRequest();
	}
 
	function processRequest() {
		$this->modifyPageHistory($this->request["pageTitle"]);
		$_SESSION = $this->session;
		//print_r($_SESSION);
	}
 
	function modifyPageHistory($page) {
		$this->session["pageHistory"] = (is_array($this->session["pageHistory"])) ? $this->session["pageHistory"] : array ();
		if ($page != end($this->session["pageHistory"])) {
			$this->session["pageHistory"][] = $page;
			reset($this->session["pageHistory"]);
		} else {}
	}

$sessionHandler = new sessionHandler($_REQUEST);
?>
