If the browser is told not to cache the page, it means, for example, if you log out and then the user hits back on the browser, the browser won't reload the logged in page from it's cache, it will try to load it again, allowing you to make sure the user is asked to log in. That's the typical reason people use it.

The error message is clear, isn't it? Yes you need to install it.

Extension-less URL rewriting is not possible in IIS6.0. If you are using IIS7.0, you can do this.

i am using IIS7.0... can you give any example coding

In fact, you can do this with any version of IIS. What you need to do, is replace all your pages with folders, and then in each folder put a default.aspx. I explained this to someone here recently, although the whole thing seems retarded to me.

Hello,
I am working with VS 2.0. i written code for dropdownlist filling using icallback event. when i use this event is working for dropdownlist. and in that page i had one button control when i click on button i am getting below error.
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
What may be the reason.
Please Help me... 
Thanks

You can use some common database for the all loggedin users and check every time when one is going to login whther someone has loggedin with a same userid or not.

You can suggest as brij said, or try to find one article on codeproject, there was a great soluation for that problem.
I am not able to find that link right now. I will send you if i got that same link .

The obvious way is in your database have a field that tells you a person is logged in, and if they are, don't allow another login. The issue with this is, you cannot be sure to catch any event that tells you a person has logged out, so you should also store a timestamp every time that user requests a page and when you check if they are logged in, also check that to see if it's been long enough to assume it has expired.
