NTLM authentication in Hierarchy

[kirubaharanbabu]

Experts,

Can anyone please let me know the answer for the below scenario.

Assuming the authentication in enabled on Parent and disabled on child

1. will the child cache the object

2. will the parent cache the authentication credentials

Thanks

1. Not by default. You can enable the caching of NTLM authenticated objects with the command:

http cache-authenticated ntlm

2. Yes. Note that you need to configure the following command on the child CE:

http append x-forwarded-for-header

This is because the parent CE (which is configured for authentication) uses the client's IP address a the key for the credentials in the authentication cache.

I would recommend you read the following reference material:
