Configuration :: Registering A Custom Section In Web.config?
Feb 12, 2010I'm getting an ConfigurationErrorsException when trying to load a custom section from my web.config.
I'm trying to register a custom section in web.config to load it later using a "Section Class".
Suppose my section is orderService, and I register it in web.config as shown:
<configuration>
<configSections>
<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
</sectionGroup>
<section name="orderService" type="orderService"/>
</configSections>
<orderService available="true" pollTimeout="00:01:00" location="abc">
</orderService>
<appSettings></appSettings>
<connectionStrings/>
Then I try to load it with:
Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
OrderService custSection = OrderService)config.GetSection("orderService"); <== The exception is thrown here (OrderService is a class that inherits from the class ConfigurationSection, and that defines a property for each orderService property, in this case: available, pollTimeout and location)
The exception says: An error occurred creating the configuration section handler for orderService: Could not load type 'orderService'. (my web.config path line 23) Does anybody know what am I doing wrong here? (I got it from the book APress: Pro ASP.NET 3.5 in C#)

Configuration :: Create A Custom Error Page In Web.config File?
Apr 14, 2010If I create a custom error page in my web.config file, how do I retrieve error details in the error page?
So with ...
<customErrors mode="On" defaultRedirect="/error/error.aspx">
<error statusCode="404" redirect="/error/404.aspx" />
</customErrors>
I am referring to errors generated by my asp.net. For example I created a sample page and wrote 'throw new Exception("some error")' as a test. How can I retrieve an instance of the exception or exception details in my "/error/error.aspx" page? Currently in my error page if I query Server.GetLastError() the return value is null.
Why Can't Add Section To Machine.config
Mar 31, 2011I would like to add this section to my machine.config in exactly the same way many articles and microsoft are suggesting:
<configuration>
<system.net>
<connectionManagement>
<add name = [URL]/>
<add name = "*" maxconnection = "2" />
</connectionManagement>
</system.net>
</configuration>
[URL] As soon as I do it though, I get this exception when trying to hit a page hosted on the IIS on the same machine: Parser Error Message: Unrecognized configuration section system.net. Source Error:
Line 9: settings that differ from their defaults.
Line 10: --><configuration>
Line 11: <system.net>
Line 12: <connectionManagement>
Line 13: <add address="*" maxconnection="24" />
Source File: C:WINDOWSMicrosoft.NETFramework64v2.0.50727Configmachine.config Line: 11 Where is the problem and how can I modify the machine.config so that I can finally control the maxconnection value?
Security :: Encrypting Section In Web.config?
May 3, 2010I am wondering how to encrypt the below information in the "web.config" file of the "Account" folder (where we have the secured pages):
[Code]....
My issue here is that even after I compiled my application (using "aspnet_compiler -v /reports c:
eports"), the information inside the web.config file of the Account folder still not encrypted, and I want to publish my site to the customer server. So, since this server is a customer server, then they can access this "web.config" file and change our web-application security behaviour (correct me if I am wrong). Basically, I don't want the customer to even have access to our secured pages when they access our web-application using the web browser. How to solve this issue?
C# - Best Way To Get The Proper Modules Section From The Web.config?
Jan 19, 2011The code I've used to get the HTTP Modules is basically
HttpModulesSection modules = ((SystemWebSectionGroup)config.GetSectionGroup("system.web")).HttpModules;
// Depending on what we need to do...
//modules.Modules.Add(CreateSomeModule());
//modules.Modules.Remove("SomeOtherModule");
This worked fine up until IIS7. The migration command %SystemRoot%system32inetsrvappcmd migrate config "website/" moves the modules into system.webServer, so my code is now updating the wrong section. Is there a built in way to get the proper module section that should be modified? Or do I have to add a check for the Request.ServerVariables["SERVER_SOFTWARE"] and return system.web/system.webServer depending on the string I get back?
MVC :: How To Respect Namespaces Section In Web.config

MachineKey Config Section Default Location?
Sep 21, 2010Where do I find the machineKey config section for ASP.NET?
I don't have one in my application Web.config, there isn't one in the root Web.config and there isn't one in my machine.config.
Does this mean there is some other default hardcoded into ASP.NET? If so, what are the defaults? (For .NET 2 and 4)
Having read this: [URL]
i was expecting to find something like this, somewhere:
<machineKey
validationKey="AutoGenerate,IsolateApps"
decryptionKey="AutoGenerate,IsolateApps"
/>
Edit: the 1.1 docs seem fairly clear wrt default values: [URL] but the 4 docs are rather ambiguous [URL]

Security :: Login SSL Confusion / Forms Authentication Section In The Web.config To Use SSL?
Apr 15, 2010I have a few pages that need to use SSL and I am confused bc I read you should set the forms authentication section in the web.config to use SSL. so if this is the case, the user logs in (login page is using ssl) the forms auth cookie is created and now if i redirect to the non ssl enable home page, does this mean the auth cookie will not be transmitted, so i can't display like a welcome module or know the username of the user who logged in?
View 6 RepliesModifying Web.Config Handlers Section Generates Extra Unneeded Entries?
Jul 19, 2010I've written a command line tool that deploys HTTP Handlers to an applications Web.Config file using a combination of System.Configuration, System.Web.Configuration and Microsoft.Web.Administration since it needs to register the handlers for both Classic and Integrated Modes as I don't know what mode end users will be using for their IIS deployments.

Configuration :: Encrypting A Custom Section Programatically
Aug 11, 2010I have a custom section in a web application that I am having trouble encrypting. I have written an external .NET program that will encrypt both .NET 1.1 & .NET 2.0 web/app configs.Up until this point in time, I have never had to encrypt any custom sections for either type of application. Anyway, the way I set it up for my web application is I wrote a class library that I import into the web application which allows me to set up and read from the custom section in the web.config. That all works fine... I added the custom section, and the web pages are able to read the values fine.
