Example of Configuration for <httpErrors>

Question

I have a Web Application in Asp.Net 4 running locally on IIS 7. I need display a Custom Page (404) and an 500 instead for the defaults page for IIS. Using this httpErrors in Web.Config

<system.webServer>
    <httpErrors>

My Site is in

C:\inetpub\wwwroot\mysite\

My Custom Error page in:

C:\inetpub\wwwroot\mysite\ErrorPages\404.htm
C:\inetpub\wwwroot\mysite\ErrorPages\505.htm

I do not understand how it works. COuld you please provide me a sample of code?

Thanks

I solved my problem with this.

<httpErrors errorMode="Custom">
    <remove statusCode="404" subStatusCode='-1' />
    <remove statusCode="500" subStatusCode='-1' />
    <error statusCode="404" path="/404.aspx" prefixLanguageFilePath="" responseMode="ExecuteURL"  />
    <error statusCode="500" path="/500.aspx" prefixLanguageFilePath="" responseMode="ExecuteURL" />
  </httpErrors>

This needs to go in Web.config, under <configuration> > <system.webServer>

e.g.

<configuration>
    <system.webServer>
        <httpErrors ...>
            // define errors in here ...
        </httpErrors>
    </system.webServer>
</configuration>

You can omit the prefixLanguageFilePath="".

Suggestion: include the parent elements so readers can see this goes inside <configuration><system.webServer>

Here is an example, hope it helps

<system.web>
<customErrors mode="RemoteOnly" defaultRedirect="default.aspx">
<error statusCode="404" redirect="~/ErrorPages/404.htm"/>
<error statusCode="500" redirect="~/ErrorPages/505.htm"/>
</customErrors>
</system.web>

Edit for comments: Here's the example I think you need

<configuration>
   <system.webServer>
      <httpErrors errorMode="DetailedLocalOnly" defaultResponseMode="File" >
         <remove statusCode="500" />
         <error statusCode="500"
            prefixLanguageFilePath="C:\Contoso\Content\errors"
            path="500.htm" />
       </httpErrors>
   </system.webServer>
</configuration>

I'm sorry, I don't understand. Could you explain?

GibboK Over a year ago

for my understanding your code works if I require a page that do not exist (with extension .aspx) ex: foo.aspx where foo.aspx does not exist on the server. I need instead work with <system.webServer> <httpErrors>.... do you have any examples?
