Env. Map on Transparent shader

Hi everybody! It's me again, sorry :D
So i have a vehicle, which have humongous sized windshield. And if i want it looked properly it need to be reflective...
Is there any way to do this? Maybe edit shader code somehow? I dont even know where it stored :D

P.S. After i've seen refraction on Frink's car i reject to believe, that reflective glass is impossible :'DDD
