Hello,

I've thought this through a bit, and I do not have the script set up to 
write to /tmp as it runs in a user folder named WebChange, where the 
temporary files are being written.

I will write a file of file names, and upon script startup, check the 
file for names to be deleted. This will additionally allow for not 
deleting files associated with time outs longer than the computer is on 
each day, as I will be able to get their time, and date from them to 
restart the proper time out periods.

Now I need to make it read a configuration file, and load urls, and 
timeouts from each line of it, and recursively call itself to load each 
url to be checked. The configuration file name needs to be passed in on 
the command line, so more than one script can run from differing 
configuration files.

Sorry about the blogging, just thinking out loud now. 8-)
