HEAD requests like this often come from social sites or search engines to 
test a url. This may or may not be the case for you, but that is my 
experience. 

Depending on the framework you are using , you should be able to handle 
HEAD requests if you want to. 

Handling the request, even if it errors does consume some resources, so 
there is likely some small impact to quota. If you don't want the systems 
hitting your site, probably the best option is robots.txt
