Response.Redirect("~/default.aspx");
}
EDIT: how do i check if the current page is defult.aspx?
I have a web app with loads of pages and most of them require some session variables in order to function.i want to put some defensive code in my master page's page_load or init events to detect if the user has a session (meaning any session variable instead of a particular variable) and if not redirect them to the homepage to start all over. whats the best way to do this? should i use session_end instead?a simple solution for this would be best.EDIT:so i am guessing the master page is the place i want to add this to?
View 3 RepliesI have some broken links on my site, and will keep having new ones on regular basis. How do i write a centralized code in web.config or something for 404 then redirect to home page? I am using aspx, vb.net and IIS7
View 1 RepliesI am using asp.net and when I type a bad url manually(in the browser) it gives me: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. I want a bad url that doesn't exist to be re-directed to the home page. How do I do this?

View 2 RepliesIs there room for issue in the following code in terms of multiple users of the same web application? I mean, I know that a purely static string will be shared across all sessions for a single ASP.NET application, but since this explicitly refers to the Current.Session, even though it is static it seems like it would always refer to the session instance of the "current user." But an error is happening that could be explained by everyone sharing the current value of Mode and thus the most recent change overwriting everyone else's mode value. (As a background: This string is in a Helpers class that is used throughout the application. I do not want to make references to Session["Mode"] throughout the application and do not want to have to pass Session["Mode"] in every method call from an aspx.cs page.)
public static string Mode
{
get
{
var value = HttpContext.Current.Session["Mode"];
return (value ?? string.Empty).ToString();
}
set
{
HttpContext.Current.Session["Mode"] = value;
}
}
I need my users are redirected to AuthError.aspx page ("You don't have the access to this page") in the case when they are authenticated but try to access the page that they cannot access (because of the role for exam). If I set up web.config so:
<authentication mode="Forms">
<forms loginUrl="~/Account/Login.aspx" timeout="2880" />
</authentication>
this is the system's wrong behaviour because an user is already authenticated and there is no need to redirect him or her to this page. But if I write here AuthError.aspx instead Login.aspx how could I redirect not-yet-authenticated user to the login page?
I have basic login functionality implemented using SQL Server and the LoginView, LoginStatus, and LoginName controls.I have two roles defined: one for Administrators and one for Users.I have two users defined, one for each role. I would like to redirect those authenticated as users to one page and those authenticated as administrators to another. Do I need to define RoleGroups to do this? Is there a good, basic way to accomplish this? I'm not sure what to do next.

I have an ASP.NET 3.5 intranet website which has a default page with a menu and when the user clicks on a menu item, I display the page for that menu item in an iframe embedded within the default page. but if the user types the URL of a page directly in the browser, then I would like to redirect him to the default page, because all the content pages do not have a menu. (Master Pages will solve this issue, but I can't use Master page here for a reason and don't want to go into those details). how to find out if user has arrived at the page directly by typing the URL or by clicking on the menu item, so that I can decide whether to redirect or not? Is this possible to find out? btw this is an intranet site and no login is required.
View 2 RepliesIn my ASP.NET MVC project i have following tag in in web.config file
<authentication mode="Forms">
<forms loginUrl="~/Account/LogOn" timeout="2880"/>
</authentication>
This causes even the authenticated users but unauthorized resource requested users to redirect to logon page. but i need only to redirect this page if user try to access unauthorized page and not already authenticated(logged on) and redirect to custom page.
Is there easy way to do this without writing custom action filter?
I am currently working on an ASP.NET MVC2 application and would just like to know the best way of achieving the following:
Each user that logs into the site pays membership fee which lasts X amount of days. I record the membership payments and the expiry dates in the database.
I would like all users to be able to login even if their membership has expired. However certain Controllers/Actions will be out of bounds to members whose membership have expired.
So my question is what is the best way to redirect users who try to access these pages when their membership has expired?
I don't really want to be calling a method that checks the membership status from each action where I don't want expired members to have access (although if this is the only way I would have to).
I thought about a custom ViewPage that inherits from System.Web.Mvc.ViewPage which I would override the OnInit function and check the membership status and redirect if necessary.
I have written a web application. All users open The default.aspx initially.
If user goes to auth/Login.aspx page and authorizes, he is redirected to auth/data.aspx
The problem is -
If user closes page and opens again, he is authorized (using cookies) but sees Default.aspx.
But because he is authorized already, is it possible that he is redirected to auth/data.aspx ?
OR
Is is possible to change the link in Master.Page to another for authorized users?
So I have a text box and a button, once the user types something in the text box, and then click button, I posted the typed text into a div control on the same page.Now my problem is that, the text box appears to have the typed text, how to resolve this type of issue? I don't want to redirect users all the time after they click the button.
View 4 RepliesIn the web.config file i have put some code in so that when users log in they will be re-directed to another part of the website which only registered users can access. for the admin part only the admin can log in and it takes him to the admin section and that works fine. it is only this that is causing me problems.
the code i inserted for which the user needs to be diverted to is:
<location path ="UserLoggedInFindUs.aspx">
<system.web>
<authorization>
<deny users ="?"/>

I have 2 sites, one the main product site the other a secure site featuring the basket and checkout processes.
When a user clicks "add item to basket" I am creating a basket in a database and then adding the items to the basket. The theory was then to store the id from the database for the basket (the basketid) in a cookie, redirect the user to secure site, use the basket id from the cookie and display the contents in the basket.
However I am having trouble getting the secure site to use the same cookie. When I redirect the users to the secure site, the basket appears empty. I need to go back to the main site and then back to secure before the cookie appears.
Here is the code for the cookie
[Code]....
And then on the secure site this is how it gets the basket ID from the cookie
[Code]....
But like I say it's having problems. I've tried replacing the cookies with session variables as well but it didn't work.
I am redirecting from a classic ASP page to an ASP.Net page on a different webserver. The landing aspx page seems to start a new session after postback i.e. my session variables which are set when the page is first hit after the redirect, are being reset after a button on the page is clicked. How do I work around this?
View 3 RepliesIt has been reported to me that a user logs into our web application and after supplying the correct credentials for themselves, are taken to the next page where they see a different customer's name at the top of the screen.
All the data at the top of our web pages is stored in session variables. The login page executes a Session.Clear statement in the Page_Load event. The user enters a username and password which is validated against our supplied database via an SQL statement. Once the user is proven to be valid, session variables are set to hold the Customer's name, as well as a few other details about them.
This is a fairly simple application, consisting of only of about 10 different pages. I am only tracking about 5 session variables per user. The session variables are initialized to either 0 or "" in the global.asax file in the Session_start routine. Upon clicking a "log out" link on any page, the login page is displayed again (executing the Session.Clear statement).
We have roughly 400 users logging into this site about once or twice a week each. The site is hosted on a server running Windows Server 2008 R2 Standard and IIS 7.
Of all 400 users, this strange session behavior has only been reported to me on a couple of occasions.
I have tried to duplicate this behavior and have not been able to. Has anyone ever heard of this? Where should I be checking for solutions? I have already checked my SQL statement and database for user authentication to make sure it is working correctly.
I got this login system where I need to set a session for when a user log's on, eacth user have 2 id's, and I need to get one of them to get the right content from my DB... So how do I get my users id's from my session's?

I am new to ASP.net and I am trying to save the state of some textboxes on redirect. I have a dashboard interface with drilldown. The main dashboard page has a date range option (textbox for both start date and end date) for the information displayed and I need to save the date range chosen by the user. I know that I can put the info into a session variable to use in the page that I am redirect to, but when I hit the 'go back' button on the drilldown page it returns to the main dashboard page and the textbox value is lost. I ahve also tried saving the viewstate, but could not get that to work either. What is the best approach to solving this problem?
edit: In case it matters, I am actually using the jQuery $(location).attr('href', url); to do the redirect because some of the chart objects I am using cover html or asp hyperlinks in IE.
Our project contains the folder structure. when I redirect to page in different folder, session automaticaly ends. How can I prevent this?
