http-headers

问题 I have to pass a meta-information in my HTTP response so I figured out that I could use the response header, for instance "X-MyData: 123456". Is that safe? I mean, there is a possibility that a client proxy remove this header? Thanks! 回答1: A client proxy could do anything it wanted, but in general would not strip any headers. Headers starting with an X- are typically reserved for nonstandard usage (i.e. no future standard will introduce a header starting X-) but a proxy may understand them

问题 This question already has answers here : Are HTTP headers case-sensitive? (6 answers) Closed 5 years ago . Perhaps I'm skimming too fast, but couldn't find this specifically documented. In my particular case, I'm wondering about the "Content-Type" header, but I'm assuming the same rules would apply to other standard headers. Are these case sensitive, and if so: Is it Content-Type or Content-type ? Is there a proper place to reference these? 回答1: Case-insensitive. Hypertext Transfer Protocol -

问题 The title is pretty self-explanatory. Is there any way to get the headers (except for Rack::Request.env[] )? 回答1: The HTTP headers are available in the Rack environment passed to your app: HTTP_ Variables: Variables corresponding to the client-supplied HTTP request headers (i.e., variables whose names begin with HTTP_). The presence or absence of these variables should correspond with the presence or absence of the appropriate HTTP header in the request. So the HTTP headers are prefixed with

问题 Whats is the python urllib equivallent of curl -u username:password status="abcd" http://example.com/update.json I did this: handle = urllib2.Request(url) authheader = "Basic %s" % base64.encodestring('%s:%s' % (username, password)) handle.add_header("Authorization", authheader) Is there a better / simpler way? 回答1: The trick is to create a password manager, and then tell urllib about it. Usually, you won't care about the realm of the authentication, just the host/url part. For example, the

问题 I have simple code that does a head request for a URL and then prints the response headers. I've noticed that on some sites, this can take a long time to complete. For example, requesting http://www.arstechnica.com takes about two minutes. I've tried the same request using another web site that does the same basic task, and it comes back immediately. So there must be something I have set incorrectly that's causing this delay. Here's the code I have: $ch = curl_init(); curl_setopt ($ch,

问题 I have a script that takes a key from $_GET['key'] , looks up the location in a database and uses the readfile together with some headers to present a download for the use. This works in Firefox but not IE8, haven't been able to test it on another IE. I get the following error in IE: "Internet Explorer cannot download download.php from www.example.com". As if it is trying to download the PHP script. $the_query = "SELECT * FROM `files` WHERE `user_id`=" . $_SESSION['user_id'] . " AND `key`='"

问题 I understand that the Accept parameter define a data type expected in a client response sent from the server, so it's used as a response header. My question is regarding the Content-type , it's used by a client to define the body format of a request sent, I always used it as part of a client request, so I have a client request where I set the headers with Accept and Content-type . And recently, I came across a project where the Content-type is defined in the response headers (so sent by the

问题 This question is extension to the question here. I am using the code here reproduced below to GZIP compress a JSONObject . String foo = "value"; ByteArrayOutputStream baos = new ByteArrayOutputStream(); GZIPOutputStream gzos = null; try { gzos = new GZIPOutputStream(baos); gzos.write(foo.getBytes("UTF-8")); } finally { if (gzos != null) try { gzos.close(); } catch (IOException ignore) {}; } byte[] fooGzippedBytes = baos.toByteArray(); I am using a DefaultHttpClient to send this compressed

问题 Is any request header added or modified to the HTTP request before forwarding to the server by a proxy server? If so, are the changes done to the same packets, or are the contents used to create new request packets with the modifications? 回答1: There are a few different types of proxy servers. Because you've mentioned request headers, I'm going to assume that you're talking about HTTP proxy servers, which forward HTTP requests, not packets. NOTE: In the special case of HTTPS requests (TLS/SSL
