	50	## Streami ng
	51
	52	You can st ream any r esponse to a file st ream.
	53
	54	```js
	55	request('h ttp://goog le.com/doo dle.png'). pipe(fs.cr eateWriteS tream('doo dle.png'))
	56	```
	57
	58	You can al so stream a file to a PUT or P OST reques t. This me thod will also check the file extension against a mapping of file exte nsions to content-ty pes (in th is case `a pplication /json`) an d use the proper `co ntent-type ` in the P UT request (if the h eaders don ’t already provide o ne).
	59
	60	```js
	61	fs.createR eadStream( 'file.json ').pipe(re quest.put( 'http://my site.com/o bj.json'))
	62	```
	63
	64	Request ca n also `pi pe` to its elf. When doing so, `content-t ype` and ` content-le ngth` are preserved in the PUT headers.
	65
	66	```js
	67	request.ge t('http:// google.com /img.png') .pipe(requ est.put('h ttp://mysi te.com/img .png'))
	68	```
	69
	70	Request em its a "res ponse" eve nt when a response i s received . The `res ponse` arg ument will be an ins tance of [ http.Incom ingMessage ](https:// nodejs.org /api/http. html#http_ class_http _incomingm essage).
	71
	72	```js
	73	request
	74	.get('ht tp://googl e.com/img. png')
	75	.on('res ponse', fu nction(res ponse) {
	76	consol e.log(resp onse.statu sCode) // 200
	77	consol e.log(resp onse.heade rs['conten t-type']) // 'image/ png'
	78	})
	79	.pipe(re quest.put( 'http://my site.com/i mg.png'))
	80	```
	81
	82	To easily handle err ors when s treaming r equests, l isten to t he `error` event bef ore piping :
	83
	84	```js
	85	request
	86	.get('ht tp://mysit e.com/dood le.png')
	87	.on('err or', funct ion(err) {
	88	consol e.log(err)
	89	})
	90	.pipe(fs .createWri teStream(' doodle.png '))
	91	```
	92
	93	Now let’s get fancy.
	94
	95	```js
	96	http.creat eServer(fu nction (re q, resp) {
	97	if (req. url === '/ doodle.png ') {
	98	if (re q.method = == 'PUT') {
	99	req. pipe(reque st.put('ht tp://mysit e.com/dood le.png'))
	100	} else if (req.m ethod === 'GET' \|\| r eq.method === 'HEAD' ) {
	101	requ est.get('h ttp://mysi te.com/doo dle.png'). pipe(resp)
	102	}
	103	}
	104	})
	105	```
	106
	107	You can al so `pipe() ` from `ht tp.ServerR equest` in stances, a s well as to `http.S erverRespo nse` insta nces. The HTTP metho d, headers , and enti ty-body da ta will be sent. Whi ch means t hat, if yo u don't re ally care about secu rity, you can do:
	108
	109	```js
	110	http.creat eServer(fu nction (re q, resp) {
	111	if (req. url === '/ doodle.png ') {
	112	var x = request( 'http://my site.com/d oodle.png' )
	113	req.pi pe(x)
	114	x.pipe (resp)
	115	}
	116	})
	117	```
	118
	119	And since `pipe()` r eturns the destinati on stream in ≥ Node 0.5.x you can do one line prox ying. :)
	120
	121	```js
	122	req.pipe(r equest('ht tp://mysit e.com/dood le.png')). pipe(resp)
	123	```
	124
	125	Also, none of this n ew functio nality con flicts wit h requests previous features, it just ex pands them .
	126
	127	```js
	128	var r = re quest.defa ults({'pro xy':'http: //localpro xy.com'})
	129
	130	http.creat eServer(fu nction (re q, resp) {
	131	if (req. url === '/ doodle.png ') {
	132	r.get( 'http://go ogle.com/d oodle.png' ).pipe(res p)
	133	}
	134	})
	135	```
	136
	137	You can st ill use in termediate proxies, the reques ts will st ill follow HTTP forw ards, etc.

	145	## Forms
	146
	147	`request` supports ` applicatio n/x-www-fo rm-urlenco ded` and ` multipart/ form-data` form uplo ads. For ` multipart/ related` r efer to th e `multipa rt` API.
	148
	149
	150	#### appli cation/x-w ww-form-ur lencoded ( URL-Encode d Forms)
	151
	152	URL-encode d forms ar e simple.
	153
	154	```js
	155	request.po st('http:/ /service.c om/upload' , {form:{k ey:'value' }})
	156	// or
	157	request.po st('http:/ /service.c om/upload' ).form({ke y:'value'} )

	159	request.po st({url:'h ttp://serv ice.com/up load', for m: {key:'v alue'}}, f unction(er r,httpResp onse,body) { /* ... * / })
	160	```
	161
	162
	163	#### multi part/form- data (Mult ipart Form Uploads)
	164
	165	For `multi part/form- data` we u se the [fo rm-data](h ttps://git hub.com/fo rm-data/fo rm-data) l ibrary by [@felixge] (https://g ithub.com/ felixge). For the mo st cases, you can pa ss your up load form data via t he `formDa ta` option .
	166
	167
	168	```js
	169	var formDa ta = {
	170	// Pass a simple k ey-value p air
	171	my_field : 'my_valu e',
	172	// Pass data via B uffers
	173	my_buffe r: new Buf fer([1, 2, 3]),
	174	// Pass data via S treams
	175	my_file: fs.create ReadStream (__dirname + '/unicy cle.jpg'),
	176	// Pass multiple v alues /w a n Array
	177	attachme nts: [
	178	fs.cre ateReadStr eam(__dirn ame + '/at tachment1. jpg'),
	179	fs.cre ateReadStr eam(__dirn ame + '/at tachment2. jpg')
	180	],
	181	// Pass optional m eta-data w ith an 'op tions' obj ect with s tyle: {val ue: DATA, options: O PTIONS}
	182	// Use c ase: for s ome types of streams , you'll n eed to pro vide "file "-related informatio n manually .

	195	}
	196	console. log('Uploa d successf ul! Serve r responde d with:', body);
	197	});
	198	```
	199
	200	For advanc ed cases, you can ac cess the f orm-data o bject itse lf via `r. form()`. T his can be modified until the request is fired on the next c ycle of th e event-lo op. (Note that this calling `f orm()` wil l clear th e currentl y set form data for that reque st.)
	201
	202	```js
	203	// NOTE: A dvanced us e-case, fo r normal u se see 'fo rmData' us age above
	204	var r = re quest.post ('http://s ervice.com /upload', function o ptionalCal lback(err, httpRespo nse, body) {...})
	205	var form = r.form();
	206	form.appen d('my_fiel d', 'my_va lue');
	207	form.appen d('my_buff er', new B uffer([1, 2, 3]));
	208	form.appen d('custom_ file', fs. createRead Stream(__d irname + ' /unicycle. jpg'), {fi lename: 'u nicycle.jp g'});
	209	```
	210	See the [f orm-data R EADME](htt ps://githu b.com/form -data/form -data) for more info rmation & examples.
	211
	212
	213	#### multi part/relat ed
	214
	215	Some varia tions in d ifferent H TTP implem entations require a newline/CR LF before, after, or both befo re and aft er the bou ndary of a `multipar t/related` request ( using the multipart option). T his has be en observe d in the . NET WebAPI version 4 .0. You ca n turn on a boundary preambleC RLF or pos tamble by passing th em as `tru e` to your request o ptions.

	275	}
	276	});
	277	```
	278
	279	If passed as an opti on, `auth` should be a hash co ntaining v alues:
	280
	281	- `user` \| \| `usernam e`
	282	- `pass` \| \| `passwor d`
	283	- `sendImm ediately` (optional)

	287	`auth(user name, pass word, send Immediatel y, bearer) `.
	288
	289	`sendImmed iately` de faults to `true`, wh ich causes a basic o r bearer
	290	authentica tion heade r to be se nt. If `se ndImmediat ely` is `f alse`, the n
	291	`request` will retry with a pr oper authe ntication header aft er receivi ng a
	292	`401` resp onse from the server (which mu st contain a `WWW-Au thenticate ` header
	293	indicating the requi red authen tication m ethod).
	294
	295	Note that you can al so specify basic aut henticatio n using th e URL itse lf, as
	296	detailed i n [RFC 173 8](http:// www.ietf.o rg/rfc/rfc 1738.txt). Simply pa ss the
	297	`user:pass word` befo re the hos t with an `@` sign:

	305	// Do m ore stuff with 'body ' here
	306	});
	307	```
	308
	309	Digest aut henticatio n is suppo rted, but it only wo rks with ` sendImmedi ately`
	310	set to `fa lse`; othe rwise `req uest` will send basi c authenti cation on the

	312
	313	Bearer aut henticatio n is suppo rted, and is activat ed when th e `bearer` value is
	314	available. The value may be ei ther a `St ring` or a `Function ` returnin g a
	315	`String`. Using a fu nction to supply the bearer to ken is par ticularly useful if
	316	used in co njunction with `defa ults` to a llow a sin gle functi on to supp ly the

	449	## Proxies
	450
	451	If you spe cify a `pr oxy` optio n, then th e request (and any s ubsequent
	452	redirects) will be s ent via a connection to the pr oxy server .
	453
	454	If your en dpoint is an `https` url, and you are us ing a prox y, then
	455	request wi ll send a `CONNECT` request to the proxy server f irst, and
	456	then use t he supplie d connecti on to conn ect to the endpoint.
	457
	458	That is, f irst it wi ll make a request li ke:
	459
	460	```
	461	HTTP/1.1 C ONNECT end point-serv er.com:80
	462	Host: prox y-server.c om
	463	User-Agent : whatever user agen t you spec ify
	464	```
	465
	466	and then t he proxy s erver make a TCP con nection to `endpoint -server`
	467	on port `8 0`, and re turn a res ponse that looks lik e:
	468
	469	```
	470	HTTP/1.1 2 00 OK
	471	```
	472
	473	At this po int, the c onnection is left op en, and th e client i s
	474	communicat ing direct ly with th e `endpoin t-server.c om` machin e.
	475
	476	See [the w ikipedia p age on HTT P Tunnelin g](https:/ /en.wikipe dia.org/wi ki/HTTP_tu nnel)
	477	for more i nformation .
	478
	479	By default , when pro xying `htt p` traffic , request will simpl y make a
	480	standard p roxied `ht tp` reques t. This is done by m aking the `url`
	481	section of the initi al line of the reque st a fully qualified url to
	482	the endpoi nt.
	483
	484	For exampl e, it will make a si ngle reque st that lo oks like:
	485
	486	```
	487	HTTP/1.1 G ET http:// endpoint-s erver.com/ some-url
	488	Host: prox y-server.c om
	489	Other-Head ers: all g o here
	490
	491	request bo dy or what ever
	492	```
	493
	494	Because a pure "http over http " tunnel o ffers no a dditional security
	495	or other f eatures, i t is gener ally simpl er to go w ith a
	496	straightfo rward HTTP proxy in this case. However, if you wou ld like
	497	to force a tunneling proxy, yo u may set the `tunne l` option to `true`.
	498
	499	You can al so make a standard p roxied `ht tp` reques t by expli citly sett ing
	500	`tunnel : false`, bu t **note t hat this w ill allow the proxy to see the traffic
	501	to/from th e destinat ion server **.
	502
	503	If you are using a t unneling p roxy, you may set th e
	504	`proxyHead erWhiteLis t` to shar e certain headers wi th the pro xy.
	505
	506	You can al so set the `proxyHea derExclusi veList` to share cer tain
	507	headers on ly with th e proxy an d not with destinati on host.
	508
	509	By default , this set is:
	510
	511	```
	512	accept
	513	accept-cha rset
	514	accept-enc oding
	515	accept-lan guage
	516	accept-ran ges
	517	cache-cont rol

	534	user-agent
	535	via
	536	```
	537
	538	Note that, when usin g a tunnel ing proxy, the `prox y-authoriz ation`
	539	header and any heade rs from cu stom `prox yHeaderExc lusiveList ` are
	540	never se nt to the endpoint s erver, but only to t he proxy s erver.
	541
	542
	543	### Contro lling prox y behaviou r using en vironment variables
	544
	545	The follow ing enviro nment vari ables are respected by `reques t`:
	546
	547	* `HTTP_P ROXY` / `h ttp_proxy`
	548	* `HTTPS_ PROXY` / ` https_prox y`
	549	* `NO_PRO XY` / `no_ proxy`
	550
	551	When `HTTP _PROXY` / `http_prox y` are set , they wil l be used to proxy n on-SSL req uests that do not ha ve an expl icit `prox y` configu ration opt ion presen t. Similar ly, `HTTPS _PROXY` / `https_pro xy` will b e respecte d for SSL requests t hat do not have an e xplicit `p roxy` conf iguration option. It is valid to define a proxy in one of th e environm ent variab les, but t hen overri de it for a specific request, using the `proxy` co nfiguratio n option. Furthermor e, the `pr oxy` confi guration o ption can be explici tly set to false / n ull to opt out of pr oxying alt ogether fo r that req uest.
	552
	553	`request` is also aw are of the `NO_PROXY `/`no_prox y` environ ment varia bles. Thes e variable s provide a granular way to op t out of p roxying, o n a per-ho st basis. It should contain a comma sepa rated list of hosts to opt out of proxyi ng. It is also possi ble to opt of proxyi ng when a particular destinati on port is used. Fin ally, the variable m ay be set to `*` to opt out of the impli cit proxy configurat ion of the other env ironment v ariables.
	554
	555	Here's som e examples of valid `no_proxy` values:
	556
	557	* `google .com` - do n't proxy HTTP/HTTPS requests to Google.
	558	* `google .com:443` - don't pr oxy HTTPS requests t o Google, but do p roxy HTTP requests t o Google.
	559	* `google .com:443, yahoo.com: 80` - don' t proxy HT TPS reques ts to Goog le, and do n't proxy HTTP reque sts to Yah oo!
	560	* `*` - i gnore `htt ps_proxy`/ `http_prox y` environ ment varia bles altog ether.

	964	## Timeout s
	965
	966	Most reque sts to ext ernal serv ers should have a ti meout atta ched, in c ase the
	967	server is not respon ding in a timely man ner. Witho ut a timeo ut, your c ode may
	968	have a soc ket open/c onsume res ources for minutes o r more.
	969
	970	There are two main t ypes of ti meouts: ** connection timeouts* * and **re ad
	971	timeouts** . A connec t timeout occurs if the timeou t is hit w hile your client is
	972	attempting to establ ish a conn ection to a remote m achine (co rrespondin g to the
	973	[connect() call][con nect] on t he socket) . A read t imeout occ urs any ti me the
	974	server is too slow t o send bac k a part o f the resp onse.
	975
	976	These two situations have wide ly differe nt implica tions for what went wrong
	977	with the r equest, so it's usef ul to be a ble to dis tinguish t hem. You c an detect
	978	timeout er rors by ch ecking `er r.code` fo r an 'ETIM EDOUT' val ue. Furthe r, you
	979	can detect whether t he timeout was a con nection ti meout by c hecking if the
	980	`err.conne ct` proper ty is set to `true`.
	981
	982	```js
	983	request.ge t('http:// IP ', {timeou t: 1500}, function(e rr) {
	984	consol e.log(err. code === ' ETIMEDOUT' );
	985	// Set to `true` if the ti meout was a connecti on timeout , `false` or
	986	// `un defined` o therwise.
	987	consol e.log(err. connect == = true);
	988	proces s.exit(0);
