http-headers

问题 I figured out the hard way that it isn't possible to add more headers to an HttpServletResponse after beginning to write the response body to the output buffer, which, I guess in some random universe could make sense even though everything is still just buffered in memory. Now the question is: Is there some trick to circumvent this somehow? Clearly, since the function resetBuffer() is available, which allows clearing of the content body without clearing the headers, there must be some way for

问题 If a HTTP server sends a reply with a Content-Length header and a message-body that is slightly larger than that length, what is the accepted way to handle this mismatch? Should I silently ignore the extra data? I don't see this specified in the HTTP/1.1 RFC, it just says that it should always match. Just seems like there could be some buggy servers out there that don't get this right. Thanks. 回答1: The length is defined by the Content-Length header field (or Chunked Encoding, or closing the

问题 I setup some custom headers using $.ajaxSetup({ headers : { 'x-custom' : 'value' } }); It will add x-custom header for all the ajax request. But I want some specific requests to NOT contain this header. I tried this, delete header from ajaxSettings before that ajax call and add it back when its completed delete $.ajaxSettings.headers["x-custom"]; $.ajax({ ... "success": function (data) { $.ajaxSettings.headers["x-custom"] = 'value'; ... } }); But I feel this is not the correct way, as the

问题 I'm pretty sure that "Expires" is valid HTTP Response Header type. But when I try to set it in my code: (this is in an ActionFilter.OnActionExecuted method) actionExecutedContext.Response.Headers.Add("Expires", (DateTime.Now + Timespan.FromDays(7)).ToString("R")); I end up with an exception: InvalidOperationException: Misused header name. Make sure request headers are used with HttpRequestMessage, response headers with HttpResponseMessage, and content headers with HttpContent objects. 回答1:

问题 How can I set a language header for my cURL request? e.g. now I get the homepage of facebook.com in dutch, probably because my server is in the Netherlands / default language send by headers?.. I prefer english before dutch in this case so I tried to set an httpheader in curl but I make no sense? What do I do wrong or what should I have to set? (zend notation) CURLOPT_HTTPHEADER => 'Accept-Language: en-US;q=0.6,en;q=0.4', Thanks in advance! 回答1: I arrived at this page looking for a way to

问题 As far as I understand, CSP can be used for all the same things as X-XSS-Protection and more. If you are using CSP, is there any good reason to use X-XSS-Protection as well? 回答1: is there any good reason to use X-XSS-Protection as well? With some doubts (see Kevin's comment below) the answer is probably yes. X-Xss-Protection activates a heuristic, reflected xss detection feature. Reflected xss comes in the form of parameters, which makes it easy to determine the scope of the potential attack.

问题 I have a custom implementation of a RESTful API for a PHP application that returns json data, and in order to communicate the status of the operation, ie whether there were failures in the request, I'm setting a custom HTTP Header with a (very tiny) json object as a string. This works well since I can send responses and easily retrieve them client side without messing with the actual data sent. The question is, are there any drawbacks I may not have realized of using this method? It doesn't

问题 Here is the code which generates pdf for me using Reportlab. Now, it just shows the pdf in the browser, and after including 'attachment' in the resonse.header ['Content-Disposition'], it downloads the pdf. But what i want is the rint option which comes you in the browser, which even allows you to choose your printer. is it possible ? data = "raghav" p = canvas.Canvas(self.response.out) p.drawString(50, 700, data) p.showPage() self.response.headers['Content-Type'] = 'application/pdf' self

问题 Our site just moved from .NET 1.1 to .NET 3.5, and in the process updated our 3rd party server controls. One of these packages uses javascript provided via WebResource.axd. These are included as normal <script src="" / > tags. Watching the traffic, however, I see that these javascript files are coming across with headers that prevent client-side caching. And we're talking a lot of javascript. The headers in question: Cache-control: no-cache, no-store pragma: no-cache Expires: -1 Are these
