Hello Every One,

I am trying to cache a long string query url with proxy_cache_key. I am not sure where I am doing wrong. I tried different proxy_cache_key patterns. Not sure where I am doing wrong. If some one can suggest me please

http://x.x.x.x/uri/splash?TF=100%25&US=A&AR=D&TD=%2450&BR=T&TS=12515f542140&OR=%2410%2F100MB&DN=BAQGBgEEBwQAAw%3D%3D&ET=TD&BE=1332d9a&BN=CS&AL=2000
