Response.Redirect - Posts Back To Self Before Redirecting?
Feb 10, 2010
Does a response.Redirect first postback to the page that's calling the redirect before actually redirecting? I don't think so but my debugging is showing me that it is.
I can see it doing so and that causes me a problem. The problem is this:
1) My page has an asp.net button on it
2) When the button is clicked, the page posts back of course. Then the following is called in the event handler method for that button:
Response.Redirect("Checkout?frpp=1"), true);
3) But I notice that when the redirect is called, it first goes back and hits the page load for this page, the page that's doing the redirecting. Well that is causing me problems because it's calling code that I don't want it to be calling again such as this:
if (!IsPostBackl)
ShowOrderItems();
so it's like I'm doing a 2nd postback:
first postback happens when you click the button, hits the event handler, runs my handler method which calls the Redirect. Redirect is called but it's doing another postback to the same page here..why?
I'm having an issue Redirecting to the same domain.
For example, the redirection takes place on ServerA.Domain.com/Folder/application.aspx. However, the program redirects me to ServerA/Folder/application.aspx.
The application works fine on this domain, but I'm forced to relogin.
What can I do to force the redirection to the same domain?
I just observed something with the .net 3.5 VS2010 Login control. It seems to response.redirect is doing something I cant explain:
[Code]....
after I hit the response.redirect all that is happening is that I stay on the login page and the URL changes to http://localhost:50324/Account/Login.aspx?ReturnUrl=%2fAccount%2fAdmin%2fApproval.aspx
Why am I not properly redirected? I used server.transfer, that put me on the right page (Approval.aspx) BUT as soonas I clicked a button, I was back at Login.aspx.
I am using the AjaxControlToolkit 3.0.30930 (the most recent). I have a very simple page with an UpdatePanel. A button on the UpdatePanel invokes Response.Redirect and passes the URL of a Click Once application on the same server. This works well if I run the website on my local system (Windows 7, IIS 7.5).
If I run the website on a remote system (Windows Server 2008, IIS 7.5, same settings) the redirect simply does not work when invoking the page from remote (using the IP address). Instead a postback is executed. Even if I use the IP address of the webserver to invoke the website locally on the webserver, the redirect does not work. Using http://localhost on the webserver the redirect works well.
I tried another test page with no UpdatePanel: The redirect works well in all scenarios.
I tried out to invoke the ClickOnce application using a link instead of Response.Redirect: The redirect works well in all scenarios, even with an UpdatePanel.

Even if setting EnablePartialRendering to false, the redirect works. This is a big clue, that the UpdatePanel causes the problem.
Im using asp.net c# (webforms) I want to add a back button to my page. (you land on this page if you incorrectly fill in a form). if javascript is enabled i want to go back via javascript, but if it is disabled i'll just do a response.redirect("~/home.aspx"). how can i implement this? is it 2 buttons? how can i hide the other in the 2 different states if so.
I have a registration page I enter the details of the customers and redirect to another page for capturing photo and I come back to the registration page. I want to retain all the values i entered when i land on the registration page.
I've been looking at google for the past few hours, trying to find an issue to a apparently simple problem. I have a UserControl named RolloverLink that basically contains a asp:LinkButton and a <img /> . I tried setting the OnClick handler like this:
[code]....
I put a breakpoint in the propagate method, but it doesnt stop there. The page does post back (it flashes), but the event doesn't get called.
I am using Javascript to alter the innerHTML attribute of a <td> and I need to get that info back in the form submittal. The <td> corrosponds to an <asp:TableCell> on the server-side, where the Text attribute is set to an initial value.
The user cannot enter the value in this particular field. Instead, its value is set by me (via client-side script) based on actions that the user performs. But this field is useless to me if I can't see its value on the server-side as well.
I'd like to avoid using a read-only textbox, because those are difficult to resize dynamically. Can an <asp:Label> be used as form data? Is there any way to achive this without letting the user manually enter the data? Or is there a simpler way to store a string as a variable somewhere and send it back as form-data?
Here's an odd one that I've never seen before. Only on IIS, not in Cassini but in all web browsers I have a button that posts back and the page_load event fires, but the actual button click event doesn't fire. there is no re-writing of the page or anything else happening.
I want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?

Recently I start having customers that are not able to login into my site. I have used the same code for months and I can login and authenticate fine it is happening on some customers not all. That is why is so hard to recreate the problem.
What is happening the customer tries to login and get redirected back to loging page. In config file I have this
[Code]....
I can not think of some else, maybe cookies not able on client, or any other security issue, IE version.
Now is it possible to make the user choose which page to be redirected to prior to login? for example the user chooses from a list the page to login to prior to login then when authenticated be redirected to this page instead of the default.aspx page. is that possible and if so how can this be done?
Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
I had a .net 4.0 vb.net page that was setting session variable and setting a hidden form value to the same value. It was a paypal buy now button. When the user selects it, they are sent to paypal for payment. If the transaction is good, they are redirected back to another page on my site and a hidden value is sent back with the invoice I originally sent them. They are sending the form value, but my session variable does not available.
From the user point of view it's all seamless.. Is it the same session? And should my session variable be available?
I am working on a website that I inherited (ASP.NET and C#), and I noticed that in almost EVERY method in the code behind of the project pages (except some helper methods), the original author uses Response.Redirect() to redirect to a page (typically home.aspx, but not always).
What is the purpose of doing this? It seems unneeded to me - at least it doesn't appear to change anything the website is doing if I keep it in or remove it.
I have a flash image slider with a button below each image. When i press that button, the user is redirected to a new page where i add that image product to my cart. The problem is that after doing the adding, i want to redirect the user back to the initial page.
note that in Firefox is working fine but in IE or Chrome it is DOWNLOADING the swf...If i comment Response.Redict(...) the user remains on this page so the click button is working well, only the redirect seems to be the problem.
Edit: The problem seems to be that Request.UrlReferrer keeps as link not the initial page containing the swf but the swf itself.
So, instead of doing redirect to:[URL] if does redirect to the swf contained on the Index.aspx page[URL]
Solved: with a session variable where i keep the initial page's url
I recently upgraded a web app to ASP.NET 4.0 , but I have to downgrade it back to 2.0, because the Response.Redirect from another web app, which is in ASP.NET 2.0, did not work.
I'm looking at creating a simple URL shortening service for our corporate intranet, and I'm curious if anyone knows if there's a maximum length for URLs returned by ASP.NET's Response.Redirect method?
