try
{
    throw new Exception();
}
catch (System.Net.Http.HttpRequestException ex) when (ex.Message.Contains(
    "404"
))
{
    return;
}
// should be something like
try
{
    throw new Exception();
}
catch (System.Net.Http.HttpRequestException ex) 
when (ex.Message.Contains("404")) // but what if this gets long and causes a link break?
{
    return;
}
