Sentry, Now With Logs (Sponsored)
 |
Failed checkouts, dropped jobs, timeouts that don’t even throw errors ➡️ these are the issues that slow your team down.
With Sentry Logs, you can trace every step, from the user’s request through your code to the log line. And because Logs connect automatically with your errors, traces, and even replays, all your debugging context lives in one place.
TLDR: Sentry has Logs. More context, fewer tabs, faster fixes, more time shipping.

HTTP vs. HTTPS

When you open a website, the difference between HTTP and HTTPS decides whether your data travels safely or in plain sight. Here’s what actually happens under the hood:
HTTP:
Sends data in plain text, anyone on the network can intercept it.
The client and server perform a simple TCP handshake: SYN, SYN-ACK, ACK
Fast but completely insecure. Passwords, tokens, and forms can all be read in transit.
HTTPS (SSL/TLS):
