SWG authentication handling

hi,

Have configured NTLM authentication in SWG, Could some help to understand the mechanisam.

- User browser requests for URL

- SWG responds back User asking for the credentials

- User browser provides the credentials

- SWG checks the credentials with AD and gets the content from the internet and serve it back to the client.

How will the second request be handled by SWG, Will SWG prompt user browser for the credentials or credentials will be saved in SWG cache
