The submitted parameters are processed by sanitize_cgi_input() at the
start of the CGI. There is no added security if we process them again at
this point.
Example: If you have a host with the name SDSL:Customer you can call
avail.cgi for the first time with no problems. But if you change the
timeperiod and resubmit, the hostname is converted to SDSL%3ACustomer
and you get an error.
