How to revert an HttpError ConfigurationElement back to "Inherited" using IIS 7 API
.net, configurationelement, iis-7, servermanager
Solution
In IIS7 and above under Management section, we can see an icon named Configuration Editor, double click and expand to
system.webserver-->webdav-->httpErrors
Right click on Default path, under
section-->Click on Revert to Parent
Then restart the website
The changes will be reverted back
Problem
Suppose I have the following `<httpErrors>` collection in a `web.config`: ``` <httpErrors> </httpErrors> ``` Yep, nice 'n empty. And in IIS 7, my HTTP errors page looks like this: Beautiful! (I've highlighted 404 simply because that's the example I'll use in a sec). Now, I run the following code: ``` errorElement["statusCode"] = 404; errorElement["subStatusCode"] = -1; errorElement["path"] = "/404.html"; httpErrorsCollection.Add(errorElement); ``` Lovely. I now have, as expected this in my `web.config`: ``` <httpErrors> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" subStatusCode="-1" prefixLanguageFilePath="" path="/404.html" /> </httpErrors> ``` Couldn't be happier. Now, in IIS 7 my HTTP errors section looks, as expected, like below: Life couldn't be sweeter at this point. Now, down the line, I want to programmatically revert my 404 error back to the state shown in the original screenshot. Logic dictates that I should `remove` my new error: ``` httpErrorsCollection.Remove(errorElement); ``` But alas, if I do this, my `web.config` looks a lot like this: ``` <httpErrors> <remove statusCode="404" subStatusCode="-1" /> </httpErrors> ``` And my IIS looks a bit like this: This is expected because of my `web.config` - but how, using `ServerManager` and all it's useful IIS 7 API, do I remove the `httpError` element entirely and revert my `web.config` back to: ``` <httpErrors> </httpErrors> ``` Any ideas?
