Package context stores values shared during a request lifetime.

Package gorilla/mux implements a request router and dispatcher.

Package manners provides a wrapper for a standard net/http server that ensures all active HTTP client have completed their current request before the server shuts down.

Predicate package used to create interpreted mini languages with Go syntax - mostly to define various predicates for configuration, e.g.

Circuit breakers start in the Standby state first, observing responses and watching location metrics.

Endpoints - final destination of the http request

Utility functions for producing errorneous http responses

Constants with common HTTP headers

Interfaces for request limiting

Simultaneous connection limiter

Tokenbucket based request rate limiter

Load balancers control how requests are distributed among multiple endpoints.

Dynamic weighted round robin load balancer

HTTP location with load balancing and pluggable middlewares

In memory request performance metrics

Middlewares can modify or intercept requests and responses

Wrapper around http.Request with additional features

Package template consolidates various templating utilities used throughout different parts of vulcan.

Package threshold contains predicates that can define various request thresholds Examples: * RequestMethod() == "GET" triggers action when request method equals "GET" * IsNetworkError() - triggers action on network errors * RequestMethod() == "GET" && Attempts <= 2 && (IsNetworkError() || ResponseCode() == 408) This predicate triggers for GET requests with maximum 2 attempts on network errors or when upstream returns special http response code 408

Package backend defines interfaces and structures controlling the proxy configuration and changes.

Etcd implementation of the backend, where all vulcand properties are implemented as directories or keys.

Provides in memory backend implementation, mostly used for test purposes
