How to best show condition (if-else) in sequence diagram.
For example, if login is successfull move on.
If login is not successful, then redirect.
Is it fine to show both the conditions in the same sequence digram? But the lifeline of an object may have to end in false condition, but the lifeline will continue if it were true.
