Whenever there is a configuration error inside the web.config, the server sends a yellow screen of death to the browser with a few lines around it. My problem is I am using impersonation and I don't want the users to see the impersonating username/password. So how can I prevent the server from showing the web.config code??

I have a custom config file in my application say my.config. Suddenly I ecnountered with some error regarding one of the settings inside the config file and the strange thing happens- my content of the config file get's rendered in the browser in the form of error. This is a big security issue for me. My question is how to prevent the content of my config files from rendering in the browser. Note I have already this setting in my web config:
<customErrors mode="Off" defaultRedirect="errors/default.aspx"/>
I am wondering why did not it redirect to error page? we had the settings turned onstill it displayed the straight error.

View 3 Repliesi have issue with browser close prompt;
"the webpage you are viewing is trying to close the window"
in ie6 i prevent this by using coding
self.opener = this;
self.close();
in ie7 and ie8 i prevent this by using coding
window.open('', '_self', '');
window.close();
but, problem is which code will prevent for all brower(ie6,7,8) asking the message.
The web app in question provides a UI for editing a client (in the business sense, not the browser sense), identified by a ClientID. I store the ClientID in Session, which gets passed from page to page, along with a number of other pieces of data in Session. Works great.
The problem is that if the user opens a new browser window using Ctrl N or File->New Window (in IE), the new window comes up with the same page as the current page, with the same session info. Then if the user navigates to a different client in the 2nd window, the ClientID in session refers to the new client. If they go back to the original browser window and save, the original client gets saved using the 2nd ClientID, and all hell breaks loose, because now the data from the two jobs are intertwined.
I have enabled trace and verified that the new browser window uses the same SessionID as the original. If an entirely new instance of IE is opened, it has a different SessionID, so is not a problem. I have not yet investigated other browsers, such as Chrome or Firefox.
Is there any way to determine if a browser instance is opened for a web app which is already open in another window or tab? Or to prevent that from happening?
My problem is am filling a form in a webpage, and click on save for instance, take the URL of mu webpage and paste it in a new window and it loads all the information I subscribed, how can I prevent that knowing that I used the Below code and it does nothing

How to prevent browser from caching image, Trsponse.Cache.NoStore didn't work
I am using asp.net 2.0 with c#.
i want a pop up to be displayed when user tries to close the browser and if user click on "no" [i.e. he don't want browser to be closed] then it prevent browser to get closed.
I have set up the Auto complete control and the web service to populate it, this web service resides within the project that uses it, it works fine on my machine (if I had a nickel for every time I heard that from a developer...) , but when I install it on Dev, the site asks for authentication, then when I select the tab with the textbox that has the Auto Complete control, it asks me for authentication again. If I remove the Auto Complete control, it no longer asks me. The funny thing is, I can enter authentication info OR just click cancel and the web service works fine.
In the IIS site on Dev and in the Web config, I have turned off authentication (in IIS I use anonymous and in the Web.config, I set it to "none") My development machine is in a domain, for some reason beyond my control, both Dev and Prod are not in a domain; both Dev and Prod machines are Server 2008. how to prevent this authentication form from showing???
i just like to ask if you have any idea of preventing the Back button of the browser to navigate back to the previous page after a user log in.Ex:After a user successfully logged in to my website and he/she hit the Back button of the browser.I want this to not redirected to the previous page instead redirected to the same page which is my Main page.Also after a user logged out to my website and again he/she hit the Back button of the browser.I also want this to not redirected to the previous page instead redirected to my login page.
View 10 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
