delete url calls url

[Rodney Tamblyn]

Sorry guys, I made a mistake. I should have been using unload URL.

The mistake came about because previously in the scripting I had been 
calling delete local xyz and delete global abc.  I wanted to delete the 
URL from the cache, and I mistakenly extended the logic to delete url, 
without considering that it might actually try to issue a delete 
command to the http server.  The web server treated it as a GET which 
was why I was seeing two calls to my script (which was generating email 
messages).
