Example:

booktitle = {in Symposium on Automotive/Avionics Systems Engineering SAASE, [http://www.jacobsschool.ucsd.edu/GordonCenter/g\_leadership/l\_summer/docs/saase/papers/MeedeniyaAleti](http://www.jacobsschool.ucsd.edu/GordonCenter/g/_leadership/l/_summer/docs/saase/papers/MeedeniyaAleti) Buhnova.pdf},

This is not a valid booktitle; the URL should not be contained. A warning should be displayed.
