Regarding the first issue, YouTube is failing to download poster images for videos. 

YouTube is a heavy application for network and it sends a lot of request(> 35)t to a remote server for various resources. YouTube App was taking a long time to receive a response from the server.

> Enable remote debugging using chrome dev tool :

mkdir -p /var/luna/preferences

After increasing the number of a tinyproxy process instance(to 10) in tinyproxy.confyoutube app started loading video smoothly. MaxClients = 10, MinSpareServers = 5, MaxSpareServers = 20, StartServers = 10

On EEL, it was working fine with existing setting MaxClients = 1,  StartServers = 1. That is a reason, changes for YouTube app are not merged in the wam-tinyproxy repository. Moreover, it doesn't make sense to a created unnecessary lot of tinyproxy for simple applications.

This task needs to be revisited and analyzed further.
