In IIS 8.5, I have a default web site with a custom page that handles 404 errors.
This custom page is default.asp, which is also the site's default document.
When a 404 error occurs and the default.asp happens to have any other error (for instance, a SQL query timeout), IIS shows only a blank page and not the actual error.
If default.asp is accessed explicitly (no 404 error), the error is correctly shown.
Steps to reproduce this problem:
Configure a web site with a 404 error document pointing to default.asp
Create a default.asp with a divide by zero error: <%=1/0%>
Access /notexists.htm in your site. A blank screen is shown.
Access /default.asp. A divide by zero error is shown, which was also expected in step 3.
Any clues?
Errors will return a status of 500-100, internal server error. So you might want to seperate out the 404 file not found, and 500-100 error pages.

I'm creating a next.js app.
And when I enter a non-existing URL, instead of seeing the default 404 page, I see this message:
Application error: a client-side exception has occurred (see the browser console for more information).
And when I open the console, all I see is this line repeating:
on-demand-entries-client.js?4540:45
GET https://localhost:3000/non-existing-url 404
eval # on-demand-entries-client.js?4540:45
eval # websocket.js?f03c:39
handleMessage # websocket.js?f03c:38
And here are the files in my pages directory. I have no custom _error.js page or 404.js page:
I'm stuck as there is no information whatsoever to tell me what's wrong in the console, and I have not created custom error pages.
What should I do?
When deploying a website via Azure web apps. I created an empty action link in _Layout.cshtml as such:<li>#Html.ActionLink("Crash", "Crash", "Home")</li>.
In Views/Home which is where all the cshtml files are stored, I did not create a specific cshtml file for Crash.
After finishing my deployment, I went to the website and clicked on Crash as it's one of the available tabs. This led to a 500.0 Internal Server Error.
I am unfamiliar with the error codes and what they represent. So I was confused as to why it threw a 500 instead of 404 File Not Found. My thought process was that if the action link leads to nowhere, then the server cannot find that corresponding file that can be served, hence it should prompt File Not Found.
Here is the detailed error information
Module ManagedPipelineHandler
Notification ExecuteRequestHandler
Handler System.Web.Mvc.MvcHandler
Error Code 0x00000000
Requested URL https://testurltesturlfake:80/Home/Crash
Physical Path C:\home\site\wwwroot\Home\Crash
Logon Method Anonymous
Logon User Anonymous
But it's giving a 500, why?
While its not affecting the site it bugs me that I can't get rid of this 404 error in the console. When I view the page I get this message:
http://myproject.dev/undefined 404 (Not Found)
And when I click to see what it refers to it points to the same line as my doctype declaration, which is a standard . I run a few php variables before this but I tried to swap them out and I still get the message.
I've set up my WP site so that it defaults to a page and this page runs on the default page.php template. Any ideas?
I have a routed page with url like http://www.example.com/2/2332/example
Now when i give a period in the url http://www.example.com/2/2332/example. I am taken to the server error page:
HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make
sure that it is spelled correctly.
I would like to redirect to the same page http://www.example.com/2/2332/example or my custom 404 error page http://www.example.com/404.aspx.
I tried debugging but its not hitting the Application_Error event in the Global.asax.cs.
Any help to solve this issue?
The breakpoint is not hit because it is not an asp.net error. It is an IIS error. You have to modify web.config to redirect to a custom error page.
I've seen a number of similar questions to this on StackOverflow and on other sites, but nothing that seems to resolve the issue I'm experiencing.
I'm trying to configure a site to return a 500 status code and a custom error page (static HTML file) for ASP.NET errors that would normally return a 500 where customErrors is set to "Off", and 404 status code for pages that our system reports as not being found (the 404 page is not a static page set via IIS, it's generated by our CMS system).
I'm part way there, but I've hit a bit of a brick wall.
At present, I'm able to return the correct 404 status code where our system returns a page with a 404 status code, but I'm now unable to return a 500 status code for ASP.NET server errors. I managed this by setting Response.TrySkipIisCustomErrors = true. My 500 errors, however, are proving more complicated. If I remove the customErrors config section from my web.config, I get the 500 error but it's the ugly ASP.NET YSOD. I can't seem to get this to point to a custom page using IIS at all, no matter what settings I use for the httpErrors config section and no matter what I set via the IIS GUI. If I add the customErrors section back, I get the custom error page as I'd expect, but I get a 200 or 302 error (depending on the value of redirectMode attribute).
Anyone got any ideas?
In terms of httpErrors config section I've tried the following so far:
Setting errorMode to "Custom" and specifying my static content for errors with a statusCode of "500" and a subStatusCode of "-1" (removing existing 500 error first)
Setting errorMode to "Detailed" and specifying my static content for errors with a statusCode of "500" and a subStatusCode of "-1" (removing existing 500 error first)
Setting existingResponse="PassThrough" for both configuration options above.
It seems you may be going above and beyond what you need to do, that is if I understand you correctly. Here is a good link
It seems like you what you need is to handle the global.asax Application_Error Event. This way you can handle it anyway you like and you dont get that ugly asp.net error screen. Any web app I create I put some code in there to handle errors so the user wont see any unformatted "blow ups"
