If libURL uses sockets callbacks, then they cannot run while while your 
hander is running.

You might try 'put URL'; see "URL" in the Transcript dictionary.  That 
may not be the best for large files, though.

However, you might also consider putting a 'wait ... with messages' in 
your loop or, better yet, use 'send ... in ...'.  See the Transcript 
dictionary and (for the latter) the primer on message mechanics at my 
web site.  If you use 'send', you can set up a cycle that checks every 
(say) 40 seconds for midnight or you can calculate the seconds until 
midnight and send off a single send (per day).  Make sure you only get 
one per midnight.

The use of 'send' allows the application to attend to button clicks 
(such as one for canceling log retrievals) and do other things.
