C# - Prevent Config Files Error To Render In Browser?

Jan 15, 2011

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.

Configuration :: How To Prevent Specific Files Being Deleted From Temporary Files

Jun 2, 2010

The majority of files in the Temporary ASP.NET File folder for a given application get deleted by ASP.NET following compilation -- .DLL and .PDB files amongst others remain.

Our compiler produces proprietary debug information files which are amongst those that get deleted.

Marking the files read-only prevents this but are there other options available?

How To Create A Common Web.config File And A Bunch Of Specific Web.config Files

Feb 16, 2011

Currently, I work on an ASP.NET project which is hosted under version control and is used on several developer machines, tester machine and production environment.

In three cases, configuration (Web.config) may be different. For example, developer and tester environments use testing SQL Server, whereas in production environment, another SQL Server is accessed, so the connection string is different in those cases.

We want to keep three versions of Web.config in subversion. But modifying each of three files every time we need to add, remove or change a common setting is annoying: it would be nice to have a common, master Web.config, which will be inherited by each of the three Web.config files.

How to set up an ASP.NET project which will use a master configuration file and different slave configuration files on different machines, thus sharing the same project/source code/configuration files in subversion?

Unable To Read Config Settings From External Config Files

Sep 1, 2010

We are experiencing some strange behaviour on one of our ASP.NET web servers (Windows 2003 64-bit). After some activity, two third-party controls are unable to run correctly. One is log4net (it does not write error messages out) and the other is a menu control (it displays eval message instead of picking up its license). The one common thread is that both controls pick up their config from external config files (linked to from web.config).

Just wondering if anyone has any thoughts on this or experienced this in any way. Is it related to file/folder rights? The server has been running fine for a while and just started exhibiting this behaviour. Perhaps it occurs around the time the worker processes are recycled.

AJAX :: Render Image From FileUpload On Browser?

Sep 28, 2010

I am developing a .Net Page that will contain a FileUpload box so a user can upload images to the site. I would like the functionality that when someone chooses a file to upload (before they actually upload the file), they can preview it on the browser. I know I can do this through some javascript magic, but is there anything that can be done using AJAX tools to gain this functionality.

What Are The Web.debug.config And Web.release.config Files For

May 7, 2010

I just upgraded to VS 2010 and MVC 2.0 and I noticed the web.config has two additional files attached to it? Are these files used to specify debug and release specific settings, so you don't clutter up the main web.config?

Does it even make sense to place a connection string in the root web.config file if I have have a local and remote one in the debug and release web.configs respectively.

Web Forms :: How To Detect And Prevent New Browser Instance

Aug 25, 2010

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?

C# - Prevent Opening Of Application On Browser Refresh?

Dec 19, 2010

I 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();
}

Prevent Multiple User Logging Into The Same Domain Using The Same Browser?

Jul 10, 2010

So its a ASP.NET problem where two users using the same machine, same browser:

User 1 logs in the domain.
User 1 changes some data without saving it.
User 2 logs in the domain in a separate tab.
User 1 switches back to his tab and saves the data.
User 1 actually saved the data into User 2!!

This is caused by the following mechanism:

Different tabs in the same browser seems to share the same session id.

We are storing user auth in cookie and the cookie is shared between tabs (same domain)

Therefore, when User 1 request to save, it is recognized as User 2 since the cookie has been updated to User 2.

So I'm wondering if there's any other methods to prevent this from happening, other than:

1. Use cookieless session so the session is embedded in uri.
2. Always include a hidden field in page to indicate which user owns the page.

How To Prevent Multiple Browser Windows From Sharing The Same Session?

Mar 25, 2010

I have ASP.net application that is basically a data entry screen for a physical inspection process. The users want to be able to have multiple browser windows open and enter data from multiple inspections concurrently. At first I was using cookie based sessions, and obviously this blew up.I switched to using cookie-less sessions, which stores the session in the URL and in testing this seemed to resolve the problem. Each browser window/tab had a different session ID, and data entered in one did not clobber data entered in the other.

However my users are more efficient at breaking things than I expected and it seems that they're still managing to get the same session between browsers sometimes. I think that they're copying/pasting the address from one tab to the other in order to open the application, but I haven't been able to verify this yet (they're at another location so I can't easily ask them).Other than telling them don't copy and paste, or convince them to only enter one at a time, how can I prevent this situation from occurring?
