http-headers

问题 It can be extremely beneficial to visually see the raw list of Http Headers that will actually be sent or received in WebAPI's HttpResponseMessage / HttpRequestMessage types. I mean just a plain old string, with each header on a new line, exactly what is generated or received. But unfortunately, it does not look like either of these types allows you to just see what actually gets generated. Instead, there are properties scattered everywhere. Some in the raw HttpResponseMessage /

问题 I'm trying to figure why the Content-Length header of php gets overwritten. This is demo.php <?php header("Content-Length: 21474836470");die; ?> a request to fetch the headers curl -I http://someserver.com/demo.php HTTP/1.1 200 OK Date: Tue, 19 Jul 2011 13:44:11 GMT Server: Apache/2.2.16 (Debian) X-Powered-By: PHP/5.3.3-7+squeeze3 Content-Length: 2147483647 Cache-Control: must-revalidate Content-Type: text/html; charset=UTF-8 See Content-Length ? It maxes out at 2147483647 bytes, that is 2GB.

问题 I have finalized a small PHP application that can serve many documents. These documents must be cacheable by clients and proxies. Since proxies can cache my results I must be extra careful because the documents I serve can have different MIMEs types (content negotiation based on $_SERVER['HTTP_ACCEPT']) and different languages (based in this order: $_POST value / $_GET value / URL / PHP session value / $_COOKIE value / $_SERVER['HTTP_ACCEPT_LANGUAGE'] / default script value). To shortly sum

问题 I have a view in my Django application that automatically creates an image using the PIL, stores it in the Nginx media server, and returns a html template with a img tag pointing to it's url. This works fine, but I notice an issue. For every 5 times I access this view, in 1 of them the image doesn't render. I did some investigation and I found something interesting, this is the HTTP response header when the image renders properly: Accept-Ranges:bytes Connection:keep-alive Content-Length:14966

问题 OK. I'm sure it does download XML files with the .xml extension, but I'm wondering what is missing in the code here to cause the .xml extenstion to be missing from the downloaded file. Note: This works in IE 6+ (didn't try WebKit based browsers or Opera) private void GenerateXmlAttachment(string xmlInStringFormat, string fileName) { // Where fileName = "someFile.xml" HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Charset = string.Empty; response

问题 I couldn't find an easy to understand answer in the specification document. Besides the simple answer I would be glad to get a reference to the specification describing this. This question is a follow up for Authorization header in null when setting its value to an Encrypted SAML 2 token. 回答1: RFC 2616, 14.8 Authorization: Authorization = "Authorization" ":" credentials RFC 2616, 11 Access Authentication: This specification adopts the definitions of [..] "credentials" from [RFC 2617].

问题 I'm building a streaming video site. The idea is that the customers should pay for a membership, login to the system, and be able to view the videos. I'm going with FlowPlayer for showing the actual videos. The problem now is, the videos need to be stored somewhere publically and the url to the .flv files needs to be passed to flowplayer for it to be able to show them. This creates a problem because anyone can do a view source, download the video, and distribute it all across the internet. I

问题 I have a custom HttpHandler in which I manually enable output compression, like so: context.Response.AppendHeader("Content-encoding", "gzip"); context.Response.Filter = new GZipStream(context.Response.Filter, CompressionMode.Compress); This works nicely for most requests, but when an exception is encountered the "Content-encoding" header disappears from the response, while the compression filter remains in place. The result is that the error page is gzip compressed, but the browser receives

问题 I am working to extract response charset in a java web app, where I am using Apache HTTP Client. For example, one possible value obtained from "Content-Type" header is text/html; charset=UTF-8 Then my code will extract all text after the "=" sign... So the charset as extracted will be UTF-8 I just wanted to know, is the above method for obtaining response charset correct? Or is there some scenario where the above code will not work? Is there something I am missing here? 回答1: Doesn't

问题 If I call header('Content-Type:text/plain; charset=ISO-8859-15'); the browser will download the file instead of showing it. Using text/html works instead. (the downloaded file is processed anyway, it's not downloading the source code) I've tried to add header('Content-Disposition:inline;'); but it was just ignored. I'm pretty clueless about what could cause this problem, any tip? The server is MAMP 1.9.6 (PHP 5.3.5, Apache/2.0.64). edit: this only happens on Chrome, it works on Firefox,
