Hi Joe: you need a command line HTTP client, which would send the URL

        http://www.ferret.noaa.gov:9090/dodsC/debug?clearCache

to the AS using HTTP GET. If you are updateing the catalog, you will need to 
also send

        http://www.ferret.noaa.gov:9090/dodsC/debug?readCatalog

I googled for "command line HTTP client" and got a lot of hits. you will 
need one specific to your OS, so you should probably sort through them. 
a couple that jumped out:

PS: you can send these kinds of questions directly to me for now if you 
want. eventually we will have a support-dodsAS email, but for now its 
quicker to send to me, since support is just forwarding them anyway.
