Nginx server detection using Firefox/Chrome extensions

Sometimes you are in the need of knowing which server is running on a particular website, and a very easy way could be usign curl, for example:

[my@server ~]$ curl -I
HTTP/1.1 200 OK
Server: nginx
Date: Wed, 20 Feb 2013 13:25:36 GMT
Content-Type: text/html; charset=UTF-8
Connection: keep-alive
Vary: Accept-Encoding
[my@server ~]$

But, what happen when you don’t have access to the shell, for example when you are on a Windows desktop, or when you are too lazy to launch and type the curl command in your linux/mac.

For those cases, there are two very useful tools that any sysadmin/developer can handle directly from the web browser to know the web server a website is using.

ServerSPY: this is a Firefox addon that shows the web server name and version, and can detect almost all kind of webservers, including Nginx.

WebServer Notifier: same as the other tool mentioned, shows the web server information of the website you are browsing, detects Nginx very well.

Do you know any other extensions for Chrome, Opera or Firefox that can detect the web server information? Please let us know so we can add the extension name to this post.
