## Request matching
Request matching is configurable and allows you to change which requests VCR
considers identical. The default behavior is `['url', method']` which means
that requests with both the same URL and method (ie POST or GET) are considered
considers identical. The default behavior is
`['method', 'scheme', 'host', 'port', 'path', 'query']` which means that
requests with both the same URL and method (ie POST or GET) are considered
identical.
This can be configured by changing the `match_on` setting.
The following options are available :
* method (for example, POST or GET)
* url (the full URL, including the protocol)
* host (the hostname of the server receiving the request)
* path (excluding the hostname)
* body (the entire request body)
* headers (the headers of the request)
* method (for example, POST or GET)
* uri (the full URI.)
* host (the hostname of the server receiving the request)
* port (the port of the server receiving the request)
* path (the path of the request)
* query (the query string of the request)
* body (the entire request body)
* headers (the headers of the request)
Backwards compatible matchers:
* url (the `uri` alias)
If these options don't work for you, you can also register your own request
matcher. This is described in the Advanced section of this README.
