Behind Proxy: Vaadin Application showing "Session Expired" pop up window

Hi,
We are facing issue in vaadin 6.8.10. we are calling vaadin application URL via service proxy. its shows session expired pop up window.When application URL is directly called without service proxy its works fine.

Vaddin version 6.8.10
icepush version 1.0.0
 

Your problem may be in proxy settings. This is a bit old tech, so I do not remember by hard the details. Check this old thread (it is a bit long), it may contain proxy setup hints that are useful for you.

Hi Tatu,

We are using external reverse Proxy (Membrane Service Proxy). Where in relative url's are configured in the proxy and complete url's are picked from service registry.

icepush requests works fine without proxy and behind proxy we are receving session time out, we have investigated the network request with and without proxy. Attaching httpFox (network trace)

Without Proxy (Works Well)

Looking at the request one thing is quite obvious that all UIDL request are Cached. Can we have some pointers Please ?

Thanks,
