Actually most (sane) proxy servers use the HTTP HEAD commando to download the header
for the file the user of the proxy requests. Then the proxy server checks the fields
in the header to decide if it should download the file once more from the web server
or use the one stored in its local cache.
In other words: This is quite normal traffic.
