Push and URL

Hi All,

I wanted to implement push to update my UI form a background thread.
Did all the basics and push seems to be working just fine.
However on loging in a push data gets appended to URL and then
navigator does not seem to understand it and I end up with an empty screen.
The big the gets added is:


Is there a wasy to not get it added to URL ?

My configuration is:

Vaadin 7.5.6
Apache Shiro
Spring Boot
