curl tricks most devs dont know — timing, DNS bypass, retry with backoff (telegra.ph)

Compiled the curl tricks I use for debugging production issues. The two biggest time savers:

The -w flag for detailed timing (DNS, connect, TLS, first byte, total) — instantly shows where latency lives
--resolve for bypassing DNS and hitting specific IPs with correct Host headers — essential for testing deployments before DNS propagation

Also covers retry with backoff, file uploads, .curlrc defaults, and JSON workflows.
