Description
Sends Get Request to HTTP Server
Usage

Arguments
host |
The host to which to send the Request e. g.: www.spiegel.de, 127.0.0.1 |
path |
The path to the file eg. /cgi/getpasswords.pl?test=best or /index.html |
referer |
something like www.myhome.org |
port |
its 80 or 8080 most frequently |
Details
It is a simple http client. So it does not take care of special chars e.g. whitspaces.

considered the last one.
