Server-side cache control headers should look like: Expires: Tue, 03 Jul 2001 06:00:00 GMT Last-Modified: {now} GMT Cache-Control: max-age=0, no-cache, must-revalidate, proxy-revalidate Avoid rewriting URLs on the client because it pollutes caches, and causes other weird semantic issues. Furthermore: Use one Cache-Control header (see rfc 2616) because behaviour with multiple entries is undefined. Also the … Read more
Here you go – note you have to decompress the gzip encoded-result you get back as per mleroy: private static readonly HttpClient _HttpClient = new HttpClient(); private static async Task<string> GetResponse(string url) { using (var request = new HttpRequestMessage(HttpMethod.Get, new Uri(url))) { request.Headers.TryAddWithoutValidation(“Accept”, “text/html,application/xhtml+xml,application/xml”); request.Headers.TryAddWithoutValidation(“Accept-Encoding”, “gzip, deflate”); request.Headers.TryAddWithoutValidation(“User-Agent”, “Mozilla/5.0 (Windows NT 6.2; WOW64; rv:19.0) Gecko/20100101 … Read more
Well, HttpResponseMessage.Headers returns an HttpResponseHeaders reference, so you should be able to use GetValues() string error = response.Headers.GetValues(“X-Error”).FirstOrDefault(); string errorCode = response.Headers.GetValues(“X-Error-Code”).FirstOrDefault();
Try: header(‘Content-Disposition: attachment; filename=”July Report.pdf”‘); or header(‘Content-Disposition: inline; filename=”July Report.pdf”‘); Another option would be to use the $_SERVER[‘PATH_INFO’] to pass your “July Report.pdf” – an example link might be: <a href=”https://stackoverflow.com/questions/2015985/report_pdf.php/July%20Report.pdf?month=07″> That file should default to saving as “July Report.pdf” – and should behave exactly like your old php script did, just change the code … Read more
You’re mixing the use cases; instantiated services ($http) cannot be used in the config phase, while providers won’t work in run blocks. From the module docs: Configuration blocks – […] Only providers and constants can be injected into configuration blocks. This is to prevent accidental instantiation of services before they have been fully configured. Run … Read more
Yes, you can redirect images and browsers will follow redirects. But you’ll generally want to keep redirection to a minimum for performance reasons, because each redirect requires a separate HTTP request, which adds server overhead and increases end-user page load time a little. The one thing you should definitely avoid is redirecting many images on … Read more
Define “necessary”. It is necessary if you want the browser to know what the type of the file is. PHP automatically sets the Content-Type header to text/html if you don’t override it so your browser is treating it as an HTML file that doesn’t contain any HTML. If your output contained any HTML you’d see … Read more
I would partially disagree with Milan’s suggestion of embedding the requested representation in the URI. If anyhow possible, URIs should only be used for addressing resources and not for tunneling HTTP methods/verbs. Eventually, specific business action (edit, lock, etc.) could be embedded in the URI if create (POST) or update (PUT) alone do not serve … Read more
This ones a little old but was high in the google ranking so I thought I would throw in the answer I found from Chrome, pdf display, Duplicate headers received from the server Basically my problem also was that the filename contained commas. Do a replace on commas to remove them and you should be … Read more
I think that is controlled by the expose_php setting in PHP.ini: expose_php = off Decides whether PHP may expose the fact that it is installed on the server (e.g. by adding its signature to the Web server header). It is no security threat in any way, but it makes it possible to determine whether you … Read more
