First thanks for your contribution.

As there is many redis adapater in the wild (predis credis, php_redis), could you rename the Redis class to CRedis ?

[vamsiikrishna]

@lyrixx I had similar idea, but I don't think creating a new class for every redis adapter will be practical . any other approach you can recommend ?

Thanks

[lyrixx]

I don't see any others.

[vamsiikrishna]

@lyrixx ok, will rename redis class to CRedis for now.

I will keep searching for any other ways. btw all redis libraries just need host and port to initiate the connection, that's why I asked if there is a better way.

Thanks
