Web Performance 101 - Redirects By Kameerath Kareem Websites are no longer just simple HTML pages with static content—they’ve evolved into a dynamic interface with features and content that are updated regularly.

Is HTTPS the Answer to Man in the Middle Attacks? | @DevOpsSummit #APM #Monitoring

Web Security Essentials: Is HTTPS the Answer to Man in the Middle Attacks? By Nilabh Mishra A Man in the Middle attack, or MITM, is a situation wherein a malicious entity can read/write data that is being transmitted between two or more systems (in most cases, between you and the website that you are surfing).
