Adding MachineKey To Web.config On Web-farm Sites / Padding Is Invalid And Cannot Be Removed

Oct 4, 2010

We (out IT partner really) recently changed some DNS for a web farmed site we have so that the two production server have round-robin DNS switching between the two. Prior to this switch we didn't really have problems with WebResource.axd files. Since the switch, when we hit the live public URL, we get an error:


Padding is invalid and cannot be removed.

When we hit the specific servers themselves, they load fine. I've researched the issue and it seems since they're sharing assets between two servers, we need to have a consistent machineKey in the web.config for each server so they can encrypt and decrypt consistently between the two. My questions are:

Can I generate a machineKey via a tool on the server, or do I need to write code to do this?

Do I just need to add the machineKey to the web.config on each server or do you think I'll need to do anything else to make the two server work together? (Both web.config's currently do not have a machineKey)

Changing Web.config From Command Line

Dec 8, 2010

I have an ASP.NET application running under IIS. I'd like to be able to change one of the web.config values in Application Settings. I know it's possible to change it programmatically as described in this answer but I'm wondering if the same thing can be accomplished from the command line.

The IIS 7 Manager allows application settings and connection strings (among other options) to be changed. My hope is there is a way to do the same via the command line for IIS 6 and/or 7.

Web.config: Changing An Application Setting With C#?

How can I change an application setting within a web.copnfig programmatically with C# (from another application, which configures the web-application)?
The following code snipped doesn't work, because AppSettings[...] is readonly!

configuration = WebConfigurationManager.OpenWebConfiguration(...);
ConfigurationSectionGroup configurationSectionGroup = (ConfigurationSectionGroup)configuration.GetSectionGroup("applicationSettings");
ConfigurationSection configurationSection = (ConfigurationSection)configurationSectionGroup.Sections[...];
configurationSection.CurrentConfiguration.AppSettings[...].value = value

Changing CustomErrors In Web.config Semi-dynamically

May 24, 2010

The basic idea is we have a test enviroment which mimics Production so customErrors="RemoteOnly". We just built a test harness that runs against the Test enviroment and detects breaks. We would like it to be able to pull back the detailed error. But we don't want to turn customErrors="On" because then it doesn't mimic Production.

I've looked around and thought a lot, and everything I've come up with isn't possible. Am I wrong about any of these points?

We can't turn customErrors on at runtime because when you call configuration.Save() - it writes the web.config to disk and now it's Off for every request.We can't symlink the files into a new top level directory with it's own web.config because we're on windows and subversion on windows doesn't do symlinks.
We can't use URL-Mapping to make an empty folder dir2 with its own web.config and make the files in dir1 appear to be in dir2 - the web.config doesn't apply. We can't copy all the aspx files into dir2 with it's own web.config because none of the links would be consistent and it's a horrible hacky solution.
We can't change customErrors in web.config based on hostname (e.g. add another dns entry to the test server) because it's not possible/supported. We can't do any virtual directory shenanigans to make it work.

If I'm not, is there a way to accomplish what I'm trying to do? Turn on customErrors site-wide under certain circumstances (dns name or even a querystring value)?

WCF / ASMX :: Toggle Between Prod And Test Web Service Without Changing Web.config?

May 5, 2010

My web.config is set up so that I don't have to change anything between deploy from UAT and Production. I can determine what machine it is running on and then programatically pick the correct connection string etc from the web.config based on the name.

Now we are adding a call to a web service which now causes us to have to make a change at deploy time. We set a "Region" flag in the web.config and then in coded an IF statement to call the appropriate webservice based on the flag so all we'd have to change is the "T" to a "P" when moving to production. But then hardcoding a web service in the application is not what we want to do. Nor do we want to change the web service address in the web.config.

Is there any way we can do something like the following to be able to not have to change the web.config at deploy?

It would be something like:

1. Grab current Machine name

2. Look in web.config for corresponding machine name web service reference (like we do for connection strings etc)

3. Use that web service in the processing.

Visual Studio :: Errors In Root Machine.config And Web.config After 2010 Installation

Jan 19, 2011

I just installed VS2010 and opened the root machine.config and web.config files for review and I found some errors. In machine.config, the following line has errors in both entries for <Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior>. When I hover the cursor over them I get a tooltip text which displays: "The element 'endpointBehaviors' has invalid child element 'Microsoft.VisualStudio.Diagnostics.ServiceModelSink.Behavior'. List of possible elements expected: '...(list of options here)...'. The same problem happens for the second appereance in tag <serviceBehaviors>.


In web.config, there is a tag called <protocols> that has an error with a tooltip text that says "The element 'system.web' has invalid child element 'protocols'. List of possible elements expected: '...(list of options here)...'.

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?

How To Determine Which Parent Config File Is Locking A Web.config Setting

Mar 15, 2011

When I open my ASP.NET site in IIS and try to open the .NET Trust Levels, I get an error message:

.NET Trust Levels There was an error while performing this operation.

Filename: ?C:inetpubwwwrootmyappweb.config
Line number: 445

Error: This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"),or set explicitly by a location tag with overrideMode="Deny" or the legacy allowOverride="false".

I've checked a few places, but I haven't found anything that seems like it would be locking that setting. Is there a systematic way of determining where that setting is locked?

I'm using IIS 7.5 and .NET 3.5 sp1.

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.
