Few questions in integrating api proxy with splunk for logging purpose

[#1]

We want to log from our proxy into our Splunk instance. The Splunk instance will be guarded by a API key for authorization. We would like to log from postFlow postClientFlow to ensure that we do not introduce additional latency. The only policy allowed in postClientFlow is MessageLoggingPolicy which unlike a serviceCallOut, only allows a TCP based connection into Splunk where I do not see a place to specify auth info.

Questions:

1. Is there any way we can specify auth in MessageLoggingPolicy?

2. Is there any way apigee can be configured to allow for serviceCallOut policy in postClientFlow?

3. Any other mechanism that you can think of to log into a remote splunk instance that requires auth without introducing additional latency?

You can make an asynchronous web request using a javascript policy. This would introduce minimal latency. Some links: http://docs.apigee.com/api-services/content/httpclient-javascript-object
