CGI, HTML, URL Check
The Z-Cron commands GETCGI, CHECKHTML and CHECKURL
can be used to check the internet connection or call a specified URL, HTML website or CGI script on a webserver.

CGI scripts can be written in many languages and may be used to generate dynamic web content, call other programs, and other
The GETCGI command calls a server script and runs another job if the script cannot be started.
CHECKHTML checks if an HTML page exists on a server. If the call does not return with HTTP status "200
OK", another job is run.
The CHECKURL command checks if a domain is reachable, and otherwise calls another Z-Cron job.
This command can be used to check if there is an internet connection, e.g. by testing if the Google homepage is reachable.
