std.net.curl.HTTPStatusException C:\D\dmd2\windows\bin\..\..\src\phobos\s
d\net\curl.d(1082): HTTP request returned status code 404 (Not Found)

What I want to do is allow certain stauts codes and I want my 
program to keep going if it receives for example 404 or 500 but 
raise an exception for lets say status code 403.

How do I achieve this?

The HTTPStatusException class has a `.status` int member that 
contains the returned status code. Is that what you're looking 
for?

Also this thread belongs in the Learn forum.

First: You post in the wrong forum section.

 How do I achieve this?

Catch that exception then do whatever you want, as in this code:

import std;

void main()
{
     try {
         get("dlang.org/aaaaaaaaaaa");
     }
     catch(CurlException ce)
     {
         if(auto e = cast(HTTPStatusException) ce)
         {
             if (e.status.among(403, 444))
                 throw new Exception("bad status, ending 
program.");

             if (e.status.among(404, 500))
                 writeln("request with status: ", e.status, ", but 
keep going.");
         }
         else if(auto e = cast(CurlTimeoutException) ce)
         {
             // TODO: implement retry
         }
         else {
             writeln(ce.msg);
         }
     }

     writeln("program finished.");
}
