I can't find any info on the following parameters that are in the [Extra Configuration] section of the proxy.cfg (NBM 3.9 SP1). Here are the parameters and their default settings from Proxy Console Screen 63:

AuthenticationDoubleFreeFix = 1
noRetryIfRequestorIsGone = 1
EnableReadAhead = 1
allow401dot1HTTPErrorCode = 1
IPAddrMgmt = 0

Does anyone know what they do?

Thanks,

Dan
