Utilize HEAD requests to the service

[machawk1]

The HTTP HEAD verb (c.f. GET, POST, etc) is useful both for testing as well as for users to get brief information without needing to wait for a potentially long process to finish. In my local instance when I

curl -I http://localhost:3000/alsummarizedtimemap/archiveIt/1068/4/summary/http://4genderjustice.org/

I am told "METHOD NOT ALLOWED". If you are caching the results at all, expressing the state of the processing could be done via an HTTP response header from a HEAD request (with the same information potentially also being present in the GET).
