How can I configure VCR to use cassette names that match the request?

I am using rspec/capybara/VCR to record tapes. Currently my tapes are automatically named to include a simplified version of the hierarchy of the test that is being run, as is the default.

I would like to configure the cassette naming scheme so that it is dependent instead on the parameters of the request, so any PUT to /abc.com with a body of XYZ would use the same tape. My thought was to configure VCR with this:

config.around_http_request do |request|
  tape_name = Digest::SHA1.hexdigest [request.method, request.uri, request.headers.to_s, request.body.to_s].join('')
  puts "Using tape #{tape_name}"
  puts "on = #{VCR.turned_on?}"
  VCR.use_cassette(tape_name, :record => :new_episodes, &request)
end

But when I do that, eventually I get the errors such as:

There is already a cassette with the same name (5d971f35322c4e0cf7d379aa39a28ef12994552f).  You cannot nest multiple cassettes with the same name.

How can I name tapes with what they contain and prevent this error?

I've just experienced the same problem and it seems that the root cause was that cassettes somehow got nested during some requests (i.e. like using a VCR.use_cassette('whatever') inside another VCR.use_cassette('whatever') block). So, I tried to put an eject_cassette prior to use_cassette and it seems to work fine, e.g. in this case:

VCR.eject_cassette(tape_name)
VCR.use_cassette(tape_name, :record => :new_episodes, &request)
