Intercept Manual Refresh In Inserting Db Action Page?
Oct 22, 2010
i have a e-commerce page which send data to last page for the payment...
In this last page, the user confirm his intention to acquire products .... In this moment, i've created a sub which insert a new order in the database...all works!...
The problem born when i try (and user could too) to manually refresh the page...the code will be processed again and a new (second) order will be inserted in the database.....it's not correct...
This page make a postback after confirm button....so control page.ispostback will not resolve problem...
How could i intercept manual refresh of this page in a secure way ?

I am using an application called "SAFE" from ASP. This application using for enter the aircraft and personal injury accident.
Once we enter all the details and click the submit button. The next page will open and show the message details like report number.
Report Number will generate depend on sequence.
If you press F5 or refresh in the same page, get the pop up message "Retry" or "Cancel".
If click the retry button, the same input details is saving and generating the next sequence report number.

DataTable dtMob = new DataTable();
dtMob = dtMobilizn.Copy();

I have created a simple dataset with my ObjcetDataSource to my SQL table named Invoices and a new FormView. My form inserts are working 100% correctly, however after some testing i noticed the insert happens again if i hit the refresh button on my browser after an initial insert. I am currently submitting the form back to itself with a success/fail message returned on the page so that the user can keep inserting more records if they choose. This is done in my Inserted behaviour.
In my ObjectDataSource_Inserting code i am setting the values of a date prior to my insert. How do i stop a second INSERT from happening when the user refreshes the browser? I thought it was what IsPostBack was used for? Here is my code:

I am using an ObjectDataSource in my FormView for INSERT.
Data inserts correctly to my backend SQL table, however as i am posting back a success/fail message to the same page, i have noticed that after a successful INSERT if it hit the Refresh button the INSERT is doubled up.
How can i stop a user pressing the Refresh button and doubling the INSERT?
Is there a setting somewhere or can i stop this programmatically within my ObjectDataSource_Inserting method perhaps?

I have an MVC app that uses [Authorize] to protect the private bits. When I select the SignOut() URL it signs me out but if I hit the back button on my browser the it goes to the secure page and even lets me use the form. The action takes place and then it shows that I'm signed out. The problem is that it performs the secured action (inserting a row into my database). Then I can use the back button again and do it all over. Am I missing something important? It seems like it could be a really big security issue.

I'm looking for a way to intercept the ASP.NET processing pipeline in such a way to be able to register event handlers to all events on the Page class. The reason is, I need to maintain a session-bound instance of a component that needs to be notified of all important Page events, starting from OnPreInit.
There's an arbitrary number of Page descendants in the application, which are not under my control. Hence I cannot use an approach like using a single custom descendant, that would notify the session-bound component, as a base class for all pages in the web application.
I don't think creating a custom IHttpHandler or IHttpModule implementation would solve the problem. Also note I cannot create a custom HttpApplication descendant.

I have a table on my page. I need to scroll down a little to get to that table. In that table i have som data that i edit and save to database. When the save is done i need to refresh the page( Response.Redirect(Request.RawUrl )) so it loads the new data to that table. When the refresh is done the page is on top again so that i need to scroll down again to see the table. This makes it very unusable for the user.
How can i refresh the page without it going back to top again? I tryed wrapping an updatepanel around the table but it didnt

I'm implement Comet in Asp.net MVC, I used timer to keep Async request in server, Async request will complete when timer elapsed 1 minute and response to client (to avoid 404 error) and then reconnect to Async Controller. I also wanna execute some Synchronous action during Async request was holding, but the problem is: When an Async action was executed and hold by using timer, the Sync Action wasn't called until Async action (comet long-live request) completed. I did test with firefox 3.6 many times, but the result is the same, so strange, Do you know why ? I have a sub some questions : To implement comet, using timer (response after some minutes elapsed) or thread (response after several time sleeping thread) to hold async request, which is better?

Lets say I have a simple controller for ASP.NET MVC I want to test. I want to test that a controller action (Foo, in this case) simply returns a link to another action (Bar, in this case).How would you test TestController.Foo? (either the first or second link)
My implementation has the same link twice. One passes the url throw ViewData[]. This seems more testable to me, as I can check the ViewData collection returned from Foo(). Even this way though, I don't know how to validate the url itself without making dependencies on routing.The controller:
public class TestController : Controller
{
public ActionResult Foo()[code].....

I have a control used in our CMS and we don't have the source code for it, what I would like to do is change the rendered output of this control.
Now, I could have a check in my base Page class that checks if the control is being used on the page and then change the html that needs to be altered, but that seems a bit excessive for just 1 usage.
So is there any other way of changing the behaviour of the control without the source code? I'm thinking not other than the way described above.

I would like to generate a 401 page if the user does not have the right permission.
The user requests a url and is redirected to the login page (I have deny all anonymous in web.config). The user logs in successfully and is redirected to the original url. However, upon permission check, it is determined that the user does not have the required permission, so I would like to generate a 401. But Forms Authentication always handles 401 and redirects the user to the login page.
To me, this isn't correct. The user has already authenticated, the user just does not have the proper authorization.
In other scenarios, such as in ajax or REST service scenario, I definitely do not want the login page - I need the proper 401 page.
So far, I've tried custom Authorize filter to return ViewResult with 401 but didn't work. I then tried a normal Action Filter, overriding OnActionExecuting, which did not work either.
What I was able to do is handle an event in global.asax, PostRequestHandlerExecute, and check for the permission then write out directly to response:
if (permissionDenied)
{
Context.Response.StatusCode = 401;
Context.Response.Clear();
Context.Response.Write("Permission Denied");
Context.Response.Flush();
[code]....
First of all, I'm not even sure if that is the right event or the place in the pipeline to do that.
Second, I want the 401 page to have a little more content. Preferably, it should be an aspx page with possibly the same master page as the rest of the site. That way, anyone browsing the site can see that the permission is denied but with the same look and feel, etc. but the ajax or service user will get the proper status code to act on.
