Richard's right. :-)

libUrl sets the User-Agent header (unless you override it by setting  
the httpHeaders yourself). It sets it to Revolution (+ platform) if  
("rev" is in the short name of me). Otherwise it sets it to Metacard.  
This is something to do with libUrl's history. (It should probably be  
updated.)

The libUrl script is usually contained in a button named "revLibUrl"  
in the revLibrary stack. I'm not sure what happens during debugging to  
alter this behavior.
