C# - Check User Authentication At Page Load?
May 18, 2010
i have an application and a user must log-in before he/she can access pages. now once the user logs in i keep the user details in a session variable (say Session["CurrentUser"]).now if a user tries to jump to a page directly i will check if the Session["CurrentUser"] has a value or not...if not then the user will be directed to the login page...my problem is that i have done this or rather say written this "Checking Code" on almost all the pages.

I want to check if user is autheneicated in control (ascx). I use HttpContext.Current.User.Identity.IsAuthenticated; for this purpose.
When I browse pages using ASP.Net Developement server -VS 2008- it works fine, But when I use IIS 7 then it always return false , even if user is authenicated.
Note that it's even work fine with IIS 6 but With IIS no hope (Classic/Integrated mode). does it related to IIS 7 or what the method that I use?

It looks like JavaScript does not have access to authentication cookies ('ASP.NET_SessionId', '.ASPXFORMSAUTH') in the http headers I can see cookies but document.cookie object does not have them.

Is there a way you can call a function, or make a file that runs before every page load. I want to be able to check if they have a valid session before showing the page.

On page load is there a way to enumerate all the nest user controls for that specific page load?
I'd like to be able to enumerate all the user controls that implement an interface, and call the interface method for the controls before asp.net passes control to thier page_load events.
The problem is from the master page level, any page in the app could be loading, and each of them could have any random user control, and I need the type reference to determine if they implement the interface, and to call the method.

In IIS 7.5 server I have a website apps.mydomain.com. Site binding for this website is:
IP: All Unassigned
Port: 80
Host name: apps.mydomain.com
In DNS there is an ip address pointing to apps.mydomain.com. Site comes up fine when browsing to this hostname.
I want to get current windows logged in username from asp.net web apps. I enabled windows authentication and disabled anonymous. Using this ASP.Net code to test:
Response.Write(Page.User.Identity.Name);
However, browsing to http://apps.mydomain.com/site/ the application pool identity shows as the Page.User.Identity.Name value and not the current windows logged in username.
If I browse to http://servername/site/ then Page.User.Identity.Name will return current windows logged in username.
Is there something else I need to configure to get the current windows logged in username when using host header?
web.config:
<?xml version="1.0"?>
<configuration>
<system.web>
<authentication mode="Windows"/>
</system.web>
</configuration>
App pool config (left out "handlers" for brevity, there's a 30000 char limit):

I am a beginner of asp.net..I currently have a login page with forgot password link button on the bottom of the screen. I am also using forms authentication to prevent an unauthorized user from accessing the other pages. The authentication seems to be working fine except for one thing. It prevents the user from accessing the password recovery page once the user click on the link button. How do I allow all users access to the login/password pages and also prevent them from viewing the other pages if they are not authenticated?The code below is to prevent from other anonymous view other pages without access. But i got no idea on how to allow them to access password recovery page...
<authentication mode="Forms">
<forms loginUrl="/Presentation/Display/Login.aspx" name=".ASPNETAUTH" protection="All" path="/" timeout="120" cookieless="UseDeviceProfile" slidingExpiration="true"/>
</authentication>
<!-- This section denies access to all files in this application except for those that you have not explicitly specified by using another setting. -->
<authorization>
<deny users="?"/>
</authorization>

On the first hit, and only the first hit, to my page having [ALLOW users="*"] in the web.config, the user is redirected to the LoginUrl, but on all subsequent visits to the page, the user IS allowed access. The user shoud ALWAYS be allowed access to this page. I suspect it is a configuration problem, so here are snippets of my web.config...

I have a user control that will basically be a header in most of my pages, but not all. I want some code in the user control to be run before the page load event of the page that holds the user control, but the page load event fires before the events in my user control. Is there a way around this?

I have an asp.net project, and I load a base aspx page to display to the user. Then I ajax in the results of an ascx component and inject it via innerHTML in javascript. I have noticed that the ascx component loads slowly on the first page load, but instantly thereafter. This is really cool, but I do not understand how this can be cached, as the contents are generated by making several db calls. Does the server send some kind of hash to compare the contents to, to see if it changed on the server or not? Is this a browser thing or an asp.net thing?

I have a page called "EDIT.ASPX" on that page it has come TextBoxes, Label and 3 User Controls. When the Edit.aspx page is loaded all the correction form Controls are loaded properly, even the User Controls loads with no problem. The problem that I am expericing is that on the User Control I have a CHECKBOX with AutoPostBack="true". Each time the user click the CheckBox the User Control disappear. NOTE: How do I fix this problem and eliminate my page control from vanshing. The user control needs to keep the same state as the Edit.aspx page when the checkbox is clicked. I need to be able to click the checkbox without loosing any data on the page rather it's the Edit Page or the User Control.
