handling Execution Timeout Expired errors

Question

I have an ASP.Net MVC application that has some reports that can throw Execution Timeout Expired errors.

I have already set a longer execution timeout in my controller and have also doubled the standard execution timeout in my connection string.

There are still instances where a few people are trying to search all records with limited input using a wild card. For these few instances I want to handle this in my catch block and display a custom message instead of having them see my generic error message that is displayed.

My question is this: Is there a way to do something like this?

catch (Exception ex)
{
    if (ex == System.TimeoutException)
    {
        Errors.ErrorOccured(ex);
        return RedirectToAction("TimeoutError", "Error");
    }
    Errors.ErrorOccured(ex);
}
return RedirectToAction("InternalServerError", "Error");

Assuming the exception being thrown is a timeout exception then yes you can do it.

try
{
   //Lengthy work here
} catch (TimeoutException ex)
{
    Errors.ErrorOccured(ex);
    return RedirectToAction("TimeoutError", "Error");
} catch (Exception ex)
{    
    Errors.ErrorOccured(ex);
    return RedirectToAction("InternalServerError", "Error");
};

//Everything succeeded so keep going...
