Patterns

Patterns can match the method, host and path of a request. Some examples:

• "/index.html" matches the path "/index.html" for any host and method.
• "GET /static/" matches a GET request whose path begins with "/static/".
• "example.com/" matches any request to the host "example.com".
• "example.com/{$}" matches requests with host "example.com" and path "/".
• "/b/{bucket}/o/{objectname...}" matches paths whose first segment is "b" and whose third segment is "o". The name "bucket" denotes the second segment and "objectname" denotes the remainder of the path.
