Does elmah handle caught exceptions as well
ELMAH has been updated to support a new feature called Signaling.
This allows you to handle exceptions how you want, while still logging them to ELMAH.
try{ int i = 5; int j = 0; i = i / j; //Throws exception}catch (Exception ex){ MyPersonalHandlingCode(ex); ErrorSignal.FromCurrentContext().Raise(ex); //ELMAH Signaling}Re-throwing exceptions can be a bad practice as it makes it difficult to trace the flow of an application. Using Signaling is a much better approach if you intended to handle the error in some fashion and simply want to document it.

A filter is the cleanest way to handle this problem. Check this solution here https://stackoverflow.com/a/5936867/965935
