# Elixor Most front-end applications communicate with backend services over the HTTP protocol. Modern browsers support two different APIs for making HTTP requests: the XMLHttpRequest interface and the fetch() API.\ \ The **Elixor** offers a simplified client HTTP API for applications that rests on the `XMLHttpRequest` interface exposed by browsers. Additional benefits include testability features, typed request and response objects, request and response interception, `Observable` apis, and streamlined error handling. Elixor supports the following features out of the box * Make [XMLHttpRequests](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest) from the browser * Supports JSONP * Intercept request and response using interceptors. * Cancel requests. * Automatically transforms for JSON data * Client side support for protecting against [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
