ASP.NET error handling for 404 pages without extension

Question

I have a website:Website Link with a problem, when it comes to extension less calls. if you try something like: This

I would like the user to go to:

here

but that is not what happens.

How can i change that?

Atm. i have this in my web.config:

    <customErrors mode="On" defaultRedirect="/Error.aspx" redirectMode="ResponseRewrite">
       <error statusCode="400" redirect="/Error.aspx?code=400" />
       <error statusCode="403" redirect="/Error.aspx?code=403" />
       <error statusCode="404" redirect="/Error.aspx?code=404" />
       <error statusCode="500" redirect="/Error.aspx?code=500" />
    </customErrors>  

and

  <system.webServer>
    <httpErrors existingResponse="PassThrough" />
    <modules runAllManagedModulesForAllRequests="true">

Some rewriting sends Error.aspx to "/findes-ikke"

After som more testing, with no luck, this is my entire web.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.web>   
    <compilation batch="false" targetFramework="4.7.1" debug="true" />
    <customErrors mode="On" defaultRedirect="/Error.aspx" redirectMode="ResponseRewrite">
      <error statusCode="404" redirect="/Error.aspx?code=404" />
    </customErrors>
  </system.web>
  <system.webServer>
    <httpErrors errorMode="Custom">
      <remove statusCode="404"/>
      <error statusCode="404" path="/findes-ikke?code=404" responseMode="ExecuteURL"/>
    </httpErrors>
  </system.webServer>
</configuration>

Answer 1

You can try the following:

change the web.config line to:

<error statusCode="404" redirect="/findes-ikke?code=404" />

You can also try to add following in web.config to redirect all http requests:

 <system.webServer>
  <httpErrors errorMode="Custom">
     <remove statusCode="404"/>
     <error statusCode="404" path="/findes-ikke?code=404" responseMode="ExecuteURL"/>
  </httpErrors>

You can also do this to redirect all error requests. Make this change in the code you have given above:

 <customErrors mode="On" defaultRedirect="/findes-ikke?code=404" redirectMode="ResponseRewrite">
