I'm using ASP.NET Membership and Form Authentication and before redirecting to the returnURL I wanted to validate it. For those unfamiliar with the workflow, basically if you request a page that requires that you are authenticated, you are redirected to a login page. In the URL string you'll see a parameter called returnURL, e.g. [URL]
Whether you use this in a redirect such as Response.Redirect(returnURL) or indirectly through the FormsAuthentication.RedirectFromLoginPage method, it passes without validating returnURL.
FormsAuthentication.RedirectFromLoginPage does have a security check that it is isn't leaving the domain, but that still doesn't stop someone from putting enough random characters to cause an error.
I tried using System.IO.File.Exists(Server.MapPath(returnURL)) but given enough illegal characters it cause Server.MapPath to error.
Note: URLEncoding doesn't work because we are not cleaning a parameter, but the primary URL.
i have created a page ate.aspx in a folder ate_secure in default directory http://localhost/. when i try to open ate.aspx, it redirects me to login.aspx, thats ok, but when i fill user name and pass and press login button, it doesn't redirect me to ate.aspx and remains at the login page with no error and all fields blank. everything was working fine till my login page ate.aspx were in the same default directory. but i wanted to use role management so i created a folder ate_secure and put ate.aspx into this folder,
A long running background process creates a text file to indicate the completion of the process. From the frontend, I'd need to check every few seconds if the text file has been created or not.
I am doing this check from http://DomainA.com However the file is created in http://DomainB.com/Mytext.txt
write a jquery script that checks for a file across domain?
PS: Currently, I am doing a ajax postback that executes a WebMethod in ASP.NET that creates HttpWebRequest. This works functionally, but I have major performance problems. So, I need a light weight way of finding if a URL is valid or not.
My requirement is that I have a few hyperlinks on a webpage and when the user clicks on these hyperlinks I should redirect the user to an asp.net web page(Default.aspx) in a different website.
For the 1st time when the user clicks on one of the hyperlinks it will launch a new browser window with the Default.aspx loaded and then if the user clicks on some other hyperlink I want to redirect the user to the existing browser window(in which deafult.aspx is already loaded)with the content related to this particular hyperlink loaded,instead of launching a new browser window/tab.
But I am not sure of how to achieve this.I wonder if I can add some js to the asp.net Default.aspx page to achieve this.
I've set Culture="auto" UICulture="auto" in @Page directive and EnableScriptGlobalization="true" EnableScriptLocalization="true" in script manager to have client culture specific date format in my textbox.
I also have a Go button on my page on which I will do a partial post back. So, I want to validate the FromDateTextBox in javascript when the Go button is clicked.
UPDATE
I know how to create a javascript click handler. But because masked editor is already validating the date on focus shift, I'm thinking there should be some boolean property (like IsValid) exposed by it which will allow me to see if the text box contains valid date.
FURTHER TRIALS
I also tried below code and Page_Validators[f].isvalid always returns true even when the date is invalid and MaskEditValidator shows me a red star near the Text box.
function isDateValid() { var b = true; for (var f = 0; f < Page_Validators.length; f++) { if (!Page_Validators[f].isvalid) b = false; } return b; } $('#GoButton').click(function() { if (!isDateValid()) { return false; } loadProducts(); });
I have a form that when submitted shows a busy animation and disables the submit button.
Anyone know how to query Microsoft's Sys.Mvc.FormValidation to see if the form passed it's test so I can prevent the busy animation showing if the form hasn't actually been submitted? Or even some other work-around? In case it's relevant - I'm using Data Annotations for my validation.
At present my client side javascript looks like this:
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 am createing user dynamially with the below code; string MyPassword = Membership.GeneratePassword(8,0).ToString(); Membership.CreateUser(TextBox7.Text, MyPassword, TextBox8.Text); but before I start creating, I would like to check if the user name is used before or not.
MVC has a method LogOn in AccountControllers. It has parameter returnUrl to redirect after login. I used this method to redirect to login page and back to previous page after logined by returnUrl parameter.My code in form view
I want to remove "returnurl=/blabla" from address bar when a user want to access to a login required page. Because I'm trying to redirect the user to a static page after login to do some selections.
Is it possible clear ReturnUrl from the server? I have a login page where the user logouts and I want to direct them to a specific page but when ReturnURL is set it overrides my redirect page.
Update:Ideally, I will only redirect a user who has just logged out versus someone who has bookmarked OR I will redirect regardless in special cases.So these are the cases:A link or bookmark -> should redirect to specified page in most case.A logout that has a returnurl -> should NOT redirect to the page,A special case -> should always redirect to my special case, i.e when a user needs to see something important
Is there a way to remove the returnurl from the logout/login status control?
For a testproject I use two Login pages. I order to do that I use a dispatcher page:
Dispatcher:
[Code]....
I then just redirect in the dispatcher to the real login-page according to the ReturnUrl. So far so good. The only problem I have is that I don't get redirected to the ReturnUrl once I'm logged in... Of course I add the ReturnUrl to the forwarded Login-Page (/Admin/Login.aspx?ReturnUrl=...).
I'm building my asp.net 4.0 website with url routing. It works great, except that I have stumbled upon one problem. The problem is that when a logged in user is on one of the non-public pages and gets loged out, the return url is set to the page he or she was previously visiting. When logging in again, the ReturnUrl is non routed url (something like login.aspx?ReturnUrl=somethingsomething). This poses a problem for some of my pages where I have a default value stored in the route; it simply doesn't get picked up with the non routed url of the ReturnUrl.The result is a broken page (404).
There is an "Add to Cart" button on product detail page, and If I click the button, it should be directed to login page.
After I login, it should be re-directed to the product detail page.
"Add to Cart" button is a CartConroller action.
In CartController.cs :
[Code]....
In AccountController.cs :
[Code]....
the product should not be added into the cart before login, so I put [Authorize] on AddToCart action.
however if I click the "add to cart" button, it directs to the login page, and if I login, it gives me an error because it lost all the AddToCart action's parameter information(e.g. Cart cart, int productId, string returnURL)
I am having an endless problem with the following.When a user logs in I want him directed to a spesific page an not the ReturnURL. How do I enforce this?I am coding in C#
I'm having trouble with the ReturnUrl property using forms authentication. If my URL is [URL], the ReturnURL value in the querystring is ignored and it always sends me to the defaultUrl value default.aspx.
I've got a couple pages in my web app that are used by external applications. They will link to the pages, and pass in various querystring values to allow my app to do the searching and return the results in the page. The problem is, if the user is not yet logged into the web app, they are sent to the login page, and the ReturnURL is truncated to include only the first QueryString value. I lose the rest of the values. So far I haven't figured out a solution to this. Here's a quick example:
The external application links the user to: [URL]
If the user is not logged in they are sent to the login page, and the current URL looks like this:
I am trying to redirect the user to login page with ReturnUrl and with querystring parameters which are already in the url there.But it is getting only first querystring parameter and not others. here is the code:Response.Redirect("~/login.aspx?ReturnUrl="+Request.RawUrl);it is showing correct in login.aspx after redirect but not returning as per querystring parametersI ave also tried other methods e.g.:
