No life without CURLs

If you’re a web server administrator – as I am – every now and then, someone yells at you “The site is down, fix it!”.

For SSL/HTTPS problems, you better use curl -Ivk, because it gives you information on the server certificate.

Have CURL installed on all your machines, Linux or Windows. Actually, add to your Windows machine, so you can work with gawk and wget too.

CURL is not the same as a real browser (especially when working with cookies/sessions), but it can help you solve 90% of typical web server problems. If the problem is browser-related, and you want to see the actual conversation between your browser and the web server, use the Ethereal network protocol analyzer.
