1`::1` is the IPv6 address for `localhost`. – ismail Jan 25 '11 at 12:18

Yes, it's an OPTIONS request, which is a feature used by some HTTP clients to query the server:
The OPTIONS method represents a request for information about the communication options available on the request/response chain identified by the Request-URI. This method allows the client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.
It's commonly used by load balancers, firewalls and proxies to check up on the status of the HTTP server, without actually requesting a resource.
The ::1 at the start is an IPv6 address.
