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.

How to redirect to login page automatically, after session time out?
In my web application, user logs in in the application, after a certain time (30 mins) session times out and login page appears only AFTER user action.
I would like to redirect the user back to the login screen automatically (before user performs any action) after session has timed out.

Your suggestions will be greatly appreciated.

There is no 'good' way to do this.  

One would be to simply include a META refresh tag set to the time you want to refresh (the 3600 is 3600 seconds/60 minutes):

<meta http-equiv="refresh" content="3600;url=http://yoursite/login.aspx"/>

Another way would be to call a Javascript or C#/VB timer and call the refresh when the timer hits a certain time.  With the C# option, you would check to make sure the session is dead.

If you included one of these methods on your page, it would be self-regulating since it would refresh every time the page refreshes which would correspond to the session refreshing.

Keeping it as simple as possible:

<meta http-equiv="refresh" content="3600;url=http://yoursite/login.aspx"/>
 
05.14.2008 at 05:28AM PDT, ID: 21563340
Problem for using <meta http-equiv="refresh" content="3600;url=http://yoursite/login.aspx"/> is
I have almost 70-100 pages in my website. It will be hectic for me to include this in all pages.

Thanks, Sp

understandable, you could use this if you were using masterpages, are you?

If not I can throw together a js example.

Javascript:
function timeout(){window.location = "http://google.com"}

call it in your html:
<body onload="setTimeout('timeout()', 5000)">

But you would still have to put this into every page... not sure how you are going to accomplish this without masterpages.
Accepted Solution
 
05.14.2008 at 06:49AM PDT, ID: 21564116
Yes, I use masterpages. But, can we give the following line master pages? I am not aware of that.
<meta http-equiv="refresh" content="3600;url=http://yoursite/login.aspx"/>
If yes, then my problem will be solved.

Alternative option:
This option I am trying to implement. I have global Pagebase.vb file that is called in all the forms. I will implement in that.
Javascript:
function timeout(){window.location = "http://google.com"}
call it in your html:
<body onload="setTimeout('timeout()', 5000)">

Regards,

If you place that in the <head> of your masterpage, it will be replicated on each page that uses the master.
