I just cannot get custom error pages to work.
I've tried so many snippets from around the web.. but to no avail.
I've seen something about disabling the net 3.5 errors which override, but not sure if it applies to me.
in my web.config I have this
<customErrors mode="On" defaultRedirect="custom404.html">
<error statusCode="404" redirect="custom404.html" />
</customErrors>
And I have an .html file there with code in within the root.
I just get the generic error 404 page.. content not found error. How can I over-ride it? Hopefully someone can point me in the right direction.
Do I need to create an .aspx file instead of .html?

We have an application hosted in IIS. The path is like domainname/ApplicationName/page.aspx. If I browse domainname/ApplicationName/dgdghdhshshs (any non existing pages without extension)it will show the default 404 page. But if I type domainname/ApplicationName/dgdghdhshshs.aspx (added .aspx extension) it will show the asp yellow pages. What I want is if any page or path which is not valid is accessed from browser, it should show the default 404 page. Is there any way for this?
Default 404 error page is coming automatically for other file extensions like .php, .html and .py. only for .aspx its showing yellow pages. Is there any option to bypass this for aspx page also?
For production environment you should set in web.config file something like this:
<customErrors mode="On" defaultRedirect="SomethingWentWrong.aspx">
<error statusCode="404" redirect="Http404ErrorPage.aspx" />
<error statusCode="500" redirect="SomethingWentWrong.aspx" />
<error statusCode="401" redirect="UnauthorizedAccess.aspx" />
</customErrors>

i am trying to put customError tag in web.config file..
still it doesn't redirect to default url
http://www.lacopainn.com/page/2/?p=dbasndwefxknyafc&wpmp_switcher=mobile
here is my site. when we enter this url it shows error of
Not Found
The requested document was not found on this server.
how can i handle this error and redirect to detault page??
please help
you need to put following tag under System.web tag in your webconfig file
<system.web>
<customErrors mode="On">
<error statusCode="404" redirect="default.aspx" />
</customErrors>
</system.web>
Hope it will fix your problem.
I've configured the web.config to show user friendly 404 and 500 errors using the following declaration:
<customErrors mode="Off" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="error.aspx"/>
<error statusCode="404" redirect="404.aspx"/>
</customErrors>
However occasionally when we're FTP'ing classes up to the server (in the App_Code folder) we may cause a compilation error that doesn't get handled gracefully and the user sees the yellow screen of death. Is there a way to hide this and show a standard holding page instead? Perhaps some adaptation of the web.config declaration above?
I know ideally we should be compiling first and publishing but we are doing a lot of dynamic changes at the moment, that make this difficult.
You can modify web.config in following way to show user-friendly messages on any error:
<customErrors mode="on" defaultRedirect="otherError.aspx" redirectMode="ResponseRewrite">
<error statusCode="500" redirect="error.aspx"/>
<error statusCode="404" redirect="404.aspx"/>
</customErrors>
Edit:
If you don't want to see compilation errors while updating your website, you can take it offline for the time of the update.
To do that, put a file named app_offline.htm in the root of your website.
The content of that file should state, that website is under maintenance/update. You can adapt content that it will be in the same style as your website.
When you are done with the updates, simply rename that file and website will work as supposed to.
For some reason, when I get an ASP.NET runtime error, it's not loading my custom error page
<customErrors mode="On" defaultRedirect="app_offline.htm" redirectMode="ResponseRewrite">
<error statusCode="404" redirect="app_offline.htm"/>
<error statusCode="500" redirect="app_offline.htm"/>
</customErrors>
That's in my web.config.
I'm still getting this though and it's not loading my error .htm page:
Server Error in '/' Application.
Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.
Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="Off"/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
</system.web>
</configuration>
I'm pretty sure that app_offline.htm is a reserved filename in ASP.NET that will always be served if present on the server.
Try renaming it to error.htm and updating your <customErrors /> block to match.
I suspect what's happening is that ASP.NET can't find your custom error page. The path to your error page file needs to be relative or absolute. So either:
<customErrors mode="On" defaultRedirect="~/app_offline.htm" redirectMode="ResponseRewrite">
<error statusCode="404" redirect="~/app_offline.htm"/>
<error statusCode="500" redirect="~/app_offline.htm"/>
</customErrors>
Or:
<customErrors mode="On" defaultRedirect="http://mysite.com/app_offline.htm" redirectMode="ResponseRewrite">
<error statusCode="404" redirect="http://mysite.com/app_offline.htm"/>
<error statusCode="500" redirect="http://mysite.com/app_offline.htm"/>
</customErrors>
Should solve your problem.
Do you get details of the actual error if you set mode="Off"? If you still get the same default error page, you might find the solution in this post:
CustomErrors mode="Off"
Problem was my site was running under .NET 3.5 when it's a 4.0 app
I also had the same issue. Main problem is related to visibility of your error pages to various users. It is controlled by the tag
Mode
as shown below
I think you have used RemoteOnly . In order to show the custom error page while running in your local machine we have to make the mode value as On. For me it is worked afterwords.
Also we can give error pages for various types of error codes. For example in below figure you can see - I have given redirecting page as CustomErrorAspxPage.aspx for file not found exception type for the status code 404.
At last in order to test this I created exceptions 1)for default exception 2)for 404 file not exists exception as shown in below figure.
Here's my web.config customErrors section (you'll notice I've switched the mode to 'On' so I can see the redirect on my localhost):
<customErrors defaultRedirect="~/Application/ServerError.aspx" mode="On" redirectMode="ResponseRewrite">
<error statusCode="403" redirect="~/Secure/AccessDenied.aspx" />
</customErrors>
and here's the code that throws:
Catch adEx As AccessDeniedException
Throw New HttpException(DirectCast(HttpStatusCode.Forbidden, Integer), adEx.Message)
End Try
and here's what I end up with:
Which is not my pretty AccessDenied.aspx page but it is a forbidden error page so at least I know my throw is working.
I've removed the entry for 403 in IIS (7.0) as a desperate last attempt and unsuprisingly that made no difference.
I've run out of ideas now so any suggestions will be gratefully appreciated!
In fact, your aspx page may not be executing at all.
Go to IIS.
Go to your default website properties.
Click on the Home Directory Tab
Click the configuration button.
Now, check if a .aspx page is registered there.
You need to specify existingResponse="PassThrough" in the system.webServer section of the httpErrors element.
<configuration>
<system.webServer>
<httpErrors existingResponse="PassThrough" />
</system.webServer>
</configuration>
