问题 There are similar questions about it, but it's not very clear how to apply the solution, and keep to receive an error. I explain. I'd like to create a simply html/js app using service worker technology. I have: Index.html js/app.js js/sw.js in app.js the code is (see //*** comments to clearify): // *** I receive always the error: // *** ERROR: The path of the provided scope ('/') is not under the max scope allowed ('/js/'). // *** Adjust the scope, move the Service Worker script, or use the

问题 How would one go about setting a header (Content Type) and rendering a twig template without renderView() method in symfony2.X controller? 回答1: You can do it returning the response as rendered view (check this sample) public function indexAction() { // a parameter which needs to be set in twig $variable = 'This is sample assignment'; $current_user = $this->user; // assume you defined a private variable in your class which contains the current user object $response = new Response(

问题 The w3.org (RFC2616) seems not to define a maximum size for chunks. But without a maximum chunk-size there is no space for the chunk-extension. There must be a maximum chunk-size, else I can't ignore the chunk-extension as I'm advised to do if it can't be understood (Quote: "MUST ignore chunk-extension extensions they do not understand" ). 回答1: Each chunk extension must begin with a semi-colon and the list of chunk extensions must end with a CRLF. When parsing the chunk-size, stop at either a

问题 trying to add an ExpiresDefault ExpiresByType to content on my website so that way it is cached. I use cachebusting in the URL (a revision number in the path) for Javascript, CSS, and images so that way I can set it to forever for these mimetypes. I have the following rules set up in apache httpd: ExpiresActive On ExpiresDefault "access plus 1 minutes" ExpiresByType image/gif "access plus 10 years" ExpiresByType image/png "access plus 10 years" ExpiresByType image/jpeg "access plus 10 years"

问题 I'm not seeing that this is possible using Requests module, but maybe I'm missing something... I need to be able to capture all the live HTTP header data that, for example, a Firefox plugin such as the creatively named Live HTTP Headers plugin Is there a method for capturing header data so that I can collect the following (or as close to the following as possible)?: https://instagram.com/oauth/authorize/?client_id=cb0096f08a3848e6a355f&redirect_uri=https://pythondev.geometryfletch.com

问题 I have a problem when use HTTP post method in the following code: let body = JSON.stringify(applicationLink); let requestHeaders = new Headers(); var headers = new Headers(); headers.set('Content-Type', ['application/json']); headers.set('Access-Control-Allow-Origin', ['*']); let reqoptions = new RequestOptions({ headers: headers }); return this._http.post(this._applicationLinksUrl + this._linkServicePath,body,reqoptions).map(res => res.json()) When I execute the code I see an error:

问题 Does the pragma no-cache mean the browser will not cache javascript scripts? e.g. Will the pragma no cache tag stop the browser from caching the jquery script? 回答1: Actually, that depends on the browser used. For modern browsers you need to add Cache-Control and Expires headers as well. response.setHeader("Cache-Control", "no-cache,no-store,must-revalidate"); response.setHeader("Pragma", "no-cache"); response.setDateHeader("Expires", 0); See also: How to control web page caching, across all

问题 We switched from citrix to HAProxy for load balancing recently. The Problem is that for some requests HAProxy started giving a 400 Error (Which used to work well on citrix). So we moved to TCP based load balancing from a HTTP based load balancing for the time being. On further investigating we found that some requests had an extra space in the HTTP header which caused the 400 error. profileID<space>:value vs profileID:value And these requests came from the android app so we are not able to

问题 I want to download an image from the 'net and set it as the users background. This works great over wi-fi, and some 3G networks, but others (T-Mobile UK, for sure) seem to compress the images before sending them. This effect is noticeable when using the browser, too - however, if you long press on an image and save it, when viewing in the gallery it is either not compressed at all, or substantially less so. I want to be able to do this in my own app. I assume it has something to do with the
