  • client generated double submit cookie, cross site request forgery prevention

    - by james
    in a double-submitted cookie csrf prevention scheme, is it necessary for the server to provide the cookie? it seems i could have javascript on the clients page generate and set a cookie "anti_csrf", then double submit that (once as a cookie, done by the browser, and once in the body of the request). a foreign domain would not be able to read or write the "anti_csrf" cookie to include it in the body of a request. is this secure, or am i overlooking something?

  • How to create a non-persistent (in memory) http cookie in C#?

    - by MatthewMartin
    I want my cookie to disappear when the user closes their brower-- I've already set some promising looking properties, but my cookies pop back to live even after closing the entire browser. HttpCookie cookie = new HttpCookie("mycookie", "abc"); cookie.HttpOnly = true; //Seems to only affect script access cookie.Secure = true; //Seems to affect only https transport What property or method call am I missing to achieve an in memory cookie?

  • DBConcurrencyException happening on second delete

    - by Malfist
    My code keeps throwing a DBConcurrencyException ("Concurrency violation: the DeleteCommand affected 0 of the expected 1 records.) when I make a second update to the data table. The problem actually happens on a table that is linked to a parent table. The two tables, CashReceipts and CashReceiptsApplyTo are displayed on the same winform, and when I delete two cash receipts the update on cash receipt apply to's table fails with the dbconcurrencyexception (the table is updated everytime the binding source [linked to a binding navigator] changes position). Here is my code: protected override void saveToDatabase() { tblCashReceiptsBindingSource.EndEdit(); tblCashReceiptsTableAdapter.Update(rentalEaseDataSet.tblCashReceipts); //update the datatable foreach (DataGridViewRow viewRow in viewApplications.Rows) { if (viewRow.Cells[colAppID.Index].Value == null || viewRow.Cells[colApplyTo.Index].Value == null) { continue; } else if ((int)viewRow.Cells[colAppID.Index].Value == -1) { insertNewRow(viewRow); } else { updateRow(viewRow); } } try { tblCashReceiptsApplyToTableAdapter.Update(rentalEaseDataSet.tblCashReceiptsApplyTo); //tblCashReceiptsApplyToTableAdapter.Fill(rentalEaseDataSet.tblCashReceiptsApplyTo); ); } catch (Exception e) { Bitmap bitmap = new Bitmap(this.Width, this.Height); this.DrawToBitmap(bitmap, new Rectangle(0, 0, this.Width, this.Height)); saveScreenshot(this.GetType().FullName, e.Message, bitmap); MessageBox.Show("There was an error saving your changes. This means that you should close the form, and re-enter the last Receipt you entered.\n\nPlease report this."); } } The insertNewRow, and updateRow are simple: private void updateRow(DataGridViewRow viewRow) { //be forgiving if ((int)viewRow.Cells[colAppID.Index].Value == -1) { insertNewRow(viewRow); return; } //find row in table, if it's not there, crash and burn RentalEaseDataSet.tblCashReceiptsApplyToRow updateRow = rentalEaseDataSet.tblCashReceiptsApplyTo.Select("ID = " + viewRow.Cells[colAppID.Index].Value.ToString())[0] as RentalEaseDataSet.tblCashReceiptsApplyToRow; updateRow.BeginEdit(); updateRow.CashReceiptsID = (int)viewRow.Cells[colCashReceipt.Index].Value; updateRow.ApplyTo = (int)viewRow.Cells[colApplyTo.Index].Value; updateRow.Paid = CurrencyToDecimal(viewRow.Cells[colPaid.Index].Value); if (viewRow.Cells[colMemo.Index].Value != null) { updateRow.Memo = viewRow.Cells[colMemo.Index].Value.ToString(); } else { updateRow.SetMemoNull(); } updateRow.EndEdit(); } private void insertNewRow(DataGridViewRow viewRow) { //be forgiving if ((int)viewRow.Cells[colAppID.Index].Value != -1) { updateRow(viewRow); return; } RentalEaseDataSet.tblCashReceiptsApplyToRow newRow = rentalEaseDataSet.tblCashReceiptsApplyTo.NewRow() as RentalEaseDataSet.tblCashReceiptsApplyToRow; newRow.CashReceiptsID = (int) viewRow.Cells[colCashReceipt.Index].Value; newRow.ApplyTo = (int) viewRow.Cells[colApplyTo.Index].Value; newRow.Paid = CurrencyToDecimal(viewRow.Cells[colPaid.Index].Value); if (viewRow.Cells[colMemo.Index].Value != null) { newRow.Memo = viewRow.Cells[colMemo.Index].Value.ToString(); } rentalEaseDataSet.tblCashReceiptsApplyTo.Rows.Add(newRow); //update the ID viewRow.Cells[colAppID.Index].Value = newRow.ID; } Any idea why it would throw that error on the second delete?

  • jQuery UI problem: why do the elements go flying around the screen?

    - by George Edison
    Yes, I know the title sounds a little suspicious. I will try to explain this the best I can... The code below is supposed to have the blue div slide down beside the red div. The first time you hit the Show the div button, it works. Also, the Hide the div works. Then when I click to show the div again, it appears to the right of where it is supposed to be! Why is this?!? Note: You can find a live example of the code here <html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Demo</title> <style type='text/css'> #red { background-color: red; width: 200px; height: 150px; position: absolute; } #blue { background-color: blue; width: 150px; height: 200px; position: absolute; display: none; } #tester_1 { top: 300px; left: 300px; position: absolute; } #tester_2 { top: 350px; left: 300px; position: absolute; } </style> </head> <script type="text/javascript" src="jquery.js"></script> <script type='text/javascript'> function Show() { $('#blue').position({ of: $('#red'), my: 'left top', at: 'right top'}).slideDown(); } function Hide() { $('#blue').hide(); } </script> <body> <div id='red'></div> <div id='blue'></div> <button id='tester_1' onclick='Show()'>Show the <kbd>div</kbd></button> <button id='tester_2' onclick='Hide()'>Hide the <kbd>div</kbd></button> </body> </html>

    - by clops
    I am creating quite a bit of XML with JavaScript which is then processed by variuos components. I would like to send this XML to some file and prompt the user to save it on their disk (all this happens in the browser at the client, no server interaction whatsoever). Is this at all possible? Google is not a lot of help here :(

  • Why won't my images align properly?

    I'm trying to make a dynamically sizable title banner, using fairly simple image tricks. I place the banner image in a table cell, and set the background-image of the table row to a one-pixel-wide repeat of the banner's right-most pixel column. Thus, the banner image appears to stretch to fit the screen width without stretching the logo. The code below is my entire page so far, and the problem is shown in a red circle in the screenshot. This is the transition where the main image ends and the one-pixel-wide background image begins. It appears that the one-pixel-wide bar at the end is compressed by one pixel - making the tops align properly, while the bottoms are one pixel off. I should add that I have checked the images more than once to make cure they the image data is correct. They are %100 accurate as far as MSPaint is concerned. <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body bgcolor="#000000"> <form id="form1" runat="server"> <div> <table style="width:100%; "> <tr style="background-image: url('Images/Banners/WebBannerWideBar.png')"> <!--WebBannerWideBar is 1x100 px--> <td> <img alt="Angry Octopus" src="Images/Banners/WebBannerWide.png" /> <!--WebBannerWide is 760x100 px--> </td> </tr> </table> </div> </form> </body> </html>

  • Make a final call to the Database when user leaves website (ASPX)?

    - by Jisaak
    I have a system set up to lock certain content in a database table so only one user can edit that content at a time. Easy enough and that part is working fine. But now I'm at a road block of how to send a request to "unlock" the content. I have the stored procedure to unlock the content, but how/where would I call it when the user just closes their browser?

  • A file's web address is different from the local file structure

    - by allanb
    I'm not sure how best to describe this (as you can clearly tell from the title) so I'll give you an example: I have a multisite Drupal installation. Each of the sites' sitemap.xml files are located on the server at /sites/example.com/files though with a browser (and to search engines) it is accessible at example.com/sitemap.xml I was wondering how this was achieved? Is this called Virtual Directory? Thank you

  • How to undelete from the SVN Repository

    - by Clay Nichols
    I accidentally deleted a major folder inside of the Tortoise-SVN Repro Browser. The working folder is unaffected. What is the recommended way to reverse that? Do I just Revert back to the previous version? Or do I need to do a Checkout to that previous version into a new folder and delete the old folder?

  • Any reason not to use USE_ETAGS with CommonMiddleware in Django?

    - by allyourcode
    The only reason I can think of is that calculating ETag's might be expensive. If pages change very quickly, the browser's cache is likely to be invalidated by the ETag. In that case, calculating the ETag would be a waste of time. On the other hand, a giving a 304 response when possible minimizes the amount of time spent in transmission. What are some good guidelines for when ETag's are likely to be a net winner when implemented with Django's CommonMiddleware?

  • Phonegap (Cordova) iOS button click

    - by JNM
    I am trying to create a very simple phone gap application for iOS. I am using query mobile. the problem is, that i can't get javascript event to fire on button click. Code i have now: <!DOCTYPE html> <html> <head> <title>Title</title> <meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1"> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="js/jquery.mobile-1.2.0.css" /> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery.mobile-1.2.0.min.js"></script> <script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { } function showAlert() { navigator.notification.alert("Cordova is working"); } </script> </head> <body> <div data-role="page" id="options" data-add-back-btn="true" data-back-btn-text="Atgal"> <div data-role="header" data-position="fixed"> <h1>Title</h1> </div> <div data-role="content"> <h1>Alert</h1> <p><a href="#" onclick="showAlert(); return false;" data-role="button">Show alert</a></p> </div> </div> </body> </html> I tried multiple solutions to fix my problem, but none of them works. When have button with # in href, it doesn't event change the color on click. When i add url, it changes color. But it never call javascript function. Another problem is, that document.addEventListener("deviceready", onDeviceReady, false); works only in the index page. If i press button in initial page which redirects to another page, OnDeviceReady function is never called. Anybody has any ideas?

  • Redirect to https login page

    - by user50622
    I have a site that has a mix of http and https pages. Under the root of the site, one folder has all the http pages and another has all the https pages. Login is over https and sends the user to the other pages. When a session expires the forms authentication redirects to the Login page but the browser uses http and the user gets a 403 error. Is there any way to override the session timeout to send it to https?

  • Rhomobile vs. Phonegap considerations

    - by NewB
    I'm debating between Phonegap and RhoMobile for cross platform mobile application development. I'm a web developer with experience in Ruby as well as the traditional web technologies (HTML, CSS, and Javascript). The backend of this application will be accessed via a web browser and built with Rails. What are my chief concerns when choosing between these platforms? Which would you recommend I go with and WHY? Thank you
