The plugins works great in tomcat 7, but have migrated to tomcat 8 and stopped working.

Could I indicate to be changed in the code to be compatible with Tomcat 8?

Thank you very much for your time and disposition.



El plugins funciona excelente en tomcat 7, pero he migrado a tomcat 8 y ha dejado de funcionar.

¿Me podría indicar que se debe modificar en el código para que sea compatible con Tomcat 8?

Muchas gracias por tu tiempo y disposición.

Every hit to manager application for status increases number of sessions by 3. Why these sessions are not cleared? How to clear these sessions?
