c# - Set network Credentials for stackExchange Redis connection multiplexer

Question

I have setup a remote redis server.

The client uses a web proxy to connect to the internet.

How do I set the StackExchange.redis ConnectionMultiplexer to use a webProxy in C#?

The following is my ConnectionMultiplexer code:

ConnectionMultiplexer redis = ConnectionMultiplexer.Connect("xxxx:6379,password=xxxxx");
