It must be fully qualified and either http or https. + +**options:** + + - `headers` - (default `{}`) http headers + - `agent` - (default: `false`) controlls keep-alive (see http://nodejs.org/api/http.html#http_http_request_options_callback) + - `followRedirects` - (default: `false`) - if true, redirects are followed (note that this only affects the result in the callback) + - `maxRedirects` - (default: `Infinity`) - limit the number of redirects allowed. + - `allowRedirectHeaders` (default: `null`) - an array of headers allowed for redirects (none if `null`). + - `gzip` (default: `false`) - automatically accept gzip and deflate encodings. This is kept completely transparent to the user. + - `cache` - (default: `null`) - `'memory'` or `'file'` to use the default built in caches or you can pass your own cache implementation. + - `timeout` (default: `false`) - times out if no response is returned within the given number of milliseconds. + - `socketTimeout` (default: `false`) - calls `req.setTimeout` internally which causes the request to timeout if no new data is seen for the given number of milliseconds. + - `retry` (default: `false`) - retry GET requests.

It has the following properties: + + - `statusCode` - a number representing the HTTP Status Code + - `headers` - an object representing the HTTP headers + - `body` - a readable stream respresenting the request body. + - `url` - the URL that was requested (in the case of redirects, this is the final url that was requested) + +**returns:** + +If the method is `GET`, `DELETE` or `HEAD`, it returns `undefined`. + +Otherwise, it returns a writable stream for the body of the request. + +## Implementing a Cache + +A `Cache` is an object with two methods: + + - `getResponse(url, callback)` - retrieve a cached response object + - `setResponse(url, response)` - cache a response object + +A cached response object is an object with the following properties: + + - `statusCode` - Number + - `headers` - Object (key value pairs of strings) + - `body` - Stream (a stream of binary data) + - `requestHeaders` - Object (key value pairs of strings) + - `requestTimestamp` - Number + +`getResponse` should call the callback with an optional error and either `null` or a cached response object, depending on whether the url can be found in the cache. Only `GET`s are cached. + +`setResponse` should just swallow any errors it has (or resport them using `console.warn`). + +A cache may also define any of the methods from `lib/cache-utils.js` to override behaviour for what gets cached. It is currently still only possible to cache "get" requests, although this could be changed. + +## License + + MIT |
