A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users. The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories.

cache behavior. Set the path pattern for the second cache behavior to the path of the login
page, and make viewer access unrestricted. Keep the default cache behavior’s settings

Hey, When I came to know that my family is under the severe clutch of financial problems I decided to quit studies, do a job, and earn money for helping in financial matters. I began to work and after a month one of my friends met me and advised me to continue the job but appear for the DVA-C01 exam. I refused the idea as I thought I'd have to join an institute but I was wrong he suggested me to prepare at PassExam4Sure with online training. I completed the training within 1 month approximately and passed the exam. After passing the exam I have got a job that was offering me much more than the previous one. For this favor, I am greatly thankful to my friend and PassExam4Sure.
