HTTP Server type 1.2.3

httptype is a program that returns the http host software of a website. It is written in Perl.
httptype reads a list of http hosts and optionally the port number for each of these. It queries each host, displaying the type of HTTP server running on that host. It reads the http_proxy and no_proxy environment variables to determine whether to use a proxy or not.
httptype reads a list of http servers and, optionally, the port number for each of these. It then queries each of the hosts and displays the HTTP server software of the host.
Input may be read from a host file if specified using the --hosts switch:
httptype --hosts [hostfile]
If hostfile is omitted or `-, httptype reads from standard input. See Format of host file for more info.
A single host may be queried by passing its name on the command line:
httptype host [port]
If port is omitted, 80 is used.
If no host file is specified through the --hosts file and no host is specified on the command line, httptype will read the list from standard input. See Format of host file for more info.
httptype will read the http_proxy environment variable and try to determine if a proxy server is being used. This setting may be overridden using the --proxy switch:
httptype --proxy proxyhost[:proxyport]
If proxyport is omitted, 80 is used.
If the proxy server is `none, no proxy is used. This is typically used to prevent httptype from using the proxy server specified by http_proxy. The --noproxy switch can be used to achieve the same.
Additionally, you may use the no_proxy environment variable to specify a comma delimited list of hosts for which httptype should not use the proxy. If httptype comes across any of these hosts, it will make a direct connection to them.
Enhancements:
