How to redirect my page to login page on Logout ?



In logout link's click event i have written Session.Abandon() that will destroy the Session state.I am also handling Session_End event that is fired afterward (written in Global.asax). But one more thing i want is that after Session ends, login page should be redirected (opened).

For that i wrote:

 Protected Sub logOut_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles logOut.Click

End Sub

This is working fine on the surface, but after applying debugging i saw that there were unexpected number of  calls to Session_Start and Session_End events for two times, then login page was opened.

Why Session_Start and Session_End was called two times ? If i left this process as it is working then may i get some serious error in future ?

Response.Redirect slow


I'm in the middle of migrating servers and on the new server Response.Redirect is extremely slow. It takes around 20 seconds for the browser to get the redirect. This is something that was quick on the existing server. It's an ASP.NET 2.0 application, both servers are running IIS6.

Additionally, if I "manually" do the redirect, it's fast. For example:

Existing way:


takes around 20 seconds on the new server

New way:

Response.Status = "302 Moved Temporarily";
Response.AddHeader("Location", url);

is fast on the new server.

Any ideas why Response.Redirect would be so slow on the new server?

Automatically redirect to HTTPS and check if SSL is active



I've set in the web.config:

    <!-- User Authentication -->
    <authentication mode="Forms">
      <forms loginUrl="~/Page/View/Content/Login.aspx" timeout="2880" requireSSL="true" />

This works fine. If there is no ssl connection, the login form doesn't continue. But I would like to check if ssl is active (in codebehind) and, if it's possible, to automatically the user to the https page if he's currently on http. (I could do this job by manually redirect with page.response("https://url.../login.aspx"); but this is not really generic. For example if the webapp is moved to another domain it doesn't work anymore... I'm looking for something like: FormsAuthentication.RedirectWithSSL(); or so... :D)


Profile not being save after redirect.



I am trying to save values into a Profile on Page1, then redirect to Page2 and access those values.  However, after the page redirects the profile values are blank as if they were never saved.   When stepping through the code I can see that they are being save on Page 1.

I suppose I could use session variables to store the information but I don't understand why saving the profile doesn't work.

private void PayWithPayPal()
        ProfileCommon profile = this.Profile;

        if (Global.CurrentUserName.Length > 0)
            profile = this.Profile.GetProfile(Global.CurrentUserName);
        profile.FirstName = uxFirstNameShipping.Text;
        profile.LastName = uxLastNameBilling.Text;
        profile.ShippingAddress.AddressLineOne = uxAddressLineOneShipping.Text;
        profile.ShippingAddress.AddressLineTwo = uxAddressLineTwoShipping.Text;
        profile.ShippingAddress.City = uxCityShipping.Text;
        profile.ShippingAddress.State = uxStateShipping.Text;
        profile.ShippingAddress.ZipCode = uxPostalCodeShipping.Text;

        Response.Redirect("~/expresspayment.aspx", false);

protected void Page_Load(object sender, EventArgs e)

Redirect to a mobile page

Hi please can anyone help? I have a simple website with a home page called defaut.aspx, also I have a page with in this site called mobile.aspx. My question is, bearing in mind that I posses very little knowledge of VB, what code do I need to place in the default.aspx to detect what kind of device someone is using and redirect them to the mobile page (mobile.aspx)? This needs to be quite up-to-date preferably for blackberry and nokia devices?


Detecting PPC device on startup page to redirect?

I was wondering (since a search didn't find any posts) if there is a way for my startup page to detect what kind of device (PocketPC or web browser specifically) is loading the page and if it is a PocketPC, then redirect to the mobile pages? I will only be using PocketPC's exclusively as a mobile device.

Thanks for any suggestions!

Adding a cookie to a response.redirect vs. httpWebRequest


Hello, I will try to be as clear as I can be.  I'm sure this question has been asked but I can't find a suitable answer for this particular situation.

I need to be able to redirect the browser to a new 3rd party page while at the same time supplying a cookie required for some form of authentication on the 3rd party site.

I have managed to get this to work in the following manner:


'SessionID is predetermined by another HttpWebRequest/Response  

Dim sessionCookie As New Cookie("ezproxy", sessionID.Substring(1), "/", ".someother.site")

Dim CookieJar As New CookieContainer


rRequest = HttpWebRequest.Create("where I want to go")

rRequest.CookieContainer = CookieJar

rRequest.Method = "GET"


'Make the request and get the response.

rResponse = rRequest.GetResponse()


'Save cookie(s)

If (rResponse.Cookies.Count <> 0) Then

For Each cook

Redirect to Security Questions if Site accessed from unrecognized computer?


I'm fairly new to ASP.NET and i'm using the Membership Provider.  I have the need to do similar to some banking sites. Baically I need to track "authorized" computers/ip's for a user.  If the user accesses the site form a recognized Computer/IP then the user is allowed into the app after successful login.  If the computer/IP is not recognized I need to redirect them to a screen to answer the security question setup in fhte Membership Provider.

Has anyone done anything like this or can anyone point me to any examples?  I did a search, but can't seem to find anything.

My idea is to maintain a list of authorized computers/IP addresses and check them on initial login.  If the IP address isn't found I can redirect them to the questions.  My concern is that they are then actually authenticated and could enter any of the site URL's as an authenticated user.

Any suggestions greatly appreciated.

Problem with Mobility Redirect


I recently tried to activate the MobilityRedirect feature in order to let users type /m to get the mobile view of a site.  It works fine on the base site of my site collection but nowhere else. I used the following command in stsadm:

stsadm -o activatefeature -name MobilityRedirect -url http://(my server name)

Am I missing something really silly?  I can't imagine that I have to activate it on each site individually.

Exit Popup and response.redirect

Hi, I have a requirement to show an Exit Popup on one of our processing pages. I am showing the exit popup by registering a client side javascript like window.onbeforeunload = ShowExitPopUp(); The popup executes fine if you close the window, or try to type in a different URL. However the issue is that my processing page is also performing a "Response.Redirect" on the server side once the process completes. When response.redirect happens the exitpopup also shows up. Is there a way to have the exit popup not show up in that case? Since my server side code is running through an UpdatePanel, so I have tried registering the following, in an attempt to remove ExitPopup from client side. However this doesn't work since server side redirection happens before end request. Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RemoveExitPopup); Has anyone faced a similar situation and handled it?
