"A potentially dangerous Request.Form value was detected from the client..." hatası neden oluşur, nasıl engellenir?

January 9, 2009 at 9:30 AM — oozturk

Form validation esnasında bir textbox'da "<>" işaretleri arasında değer görülürse hata oluşur. Bu web sitelerinin ve sayfalarının korunması amaçlı bir önlem olarak .net içinde mevcuttur. Bu tür girişlerin izin verilmesini, engellenmemesini, hata oluşmamasını istiyorsanız yapmanız gereken tek birşey var. Web sayfasının (ASPX dosyasının) ilk satırında validateRequest="false" ibaresinin belirtilmesi gerekiyor o kadar.

Yani eğer;

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MyForm.aspx.vb" Inherits="Proj.MyForm"%>

Gibi bir kodunuz varsa bunu:

<%@ Page Language="vb" AutoEventWireup="false" Codebehind="MyForm.aspx.vb" Inherits="Proj.MyForm" ValidateRequest="false"%>

Şeklinde değiştirmeniz bu hatanın oluşmasını engeller.

I admire what you have done here. I like the part where you say you are doing this to give back but I would assume by all the comments that this is working for you as well.

I admire the valuable information you offer in your articles. I'm very excited and longing for your next article. Hopefully I will get it this week. Really value this post especially. It's hard to separate the very good from the bad these days, but I believe you've pushed the right key! Is it possible to write a guest articles here? I would like to write a one or two articles here.
