I have a link on a website on click of which a new website in a new tab gets opened.

While opening the site in new tab, i set a flag and open the new site.

My question is when i close new tab ie site i want to reset the flag, so that i can check if the flag is not yet RESET (new site is still opened) or its done. If its still opened in tab then i cant open another site on clicking the link.

So when i close the tab that flag must be reset and send to main website, so that i can check its status in main website! How to do this??

Can anybody Help??

You can try making use of the PostBackUrl and PreviousPage properties to acheive this.

Post To Another Page in ASP.NET 2.0[^]

I am not sure if it has "set" access to properties using Previous page..You may try it with this article's help.

You could use a session variable to hold the flag value, and setup a page with a querystring value that allows the session var to get set when the other web site calls the page. Of course, this will only work if you have control of both web sites.

There also may be some sort of DOM trickery you can take advantage of, but that's going to require some delicate googling skills.

Then again (if you have control of both web sites), you could always setup WCF communications between them.

I don't have any inter-site communications experience to speak of, so I could only guess at search phrases.
