阅读更多关于 How can I get browser authentication popup?

问题 Can anyone tell me, how can I get this browser authentication window ? 回答1: This popup is part of the HTTP-Authentication. In order to get it, you need to enable it in your web server. As Wikipedia puts it: When the server wants the user agent to authenticate itself towards the server, it can send a request for authentication. This request should be sent using the HTTP 401 Not Authorized response code containing a WWW-Authenticate HTTP header. The WWW-Authenticate header for basic

How can I tell when HTTP Headers have been sent in an ASP.NET application?

阅读更多关于 How can I tell when HTTP Headers have been sent in an ASP.NET application?

问题 Long story short, I have an ASP.NET application I'm trying to debug and at some point, in very particular circumstances, the application will throw exceptions at a Response.Redirect() stating: "Cannot redirect after HTTP headers have been sent." Which I more or less get, except that I cannot figure out where the headers were sent. Is there something to look for in an ASP.NET application that will indicate that the HTTP headers have been sent? BONUS DIFFICULTY: The ASP.NET app is still in .NET

How to set HttpHeader on individual request using HttpClient

阅读更多关于 How to set HttpHeader on individual request using HttpClient

I have an HttpClient that is shared across multiple threads: public static class Connection { public static HttpClient Client { get; } static Connection() { Client = new HttpClient { BaseAddress = new Uri(Config.APIUri) }; Client.DefaultRequestHeaders.Add("Connection", "Keep-Alive"); Client.DefaultRequestHeaders.Add("Keep-Alive", "timeout=600"); Client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); } } It has some default headers I put onto each request. However, when I use it, I want to add on a header for just that request: var client = Connection

AWS Elastic Beanstalk: HTTP Header not appearing in Flask application

阅读更多关于 AWS Elastic Beanstalk: HTTP Header not appearing in Flask application

I have a small Flask application that I want to run on AWS Elastic Beanstalk. The application deploys and runs fine but I've noticed that a custom HTTP Header (HTTP_CUSTOM_TOKEN) is not present in request.headers . I'm assuming I'm missing something from the Apache configuration but am not very familiar with that environment. What you need is something similar to what @Fartash suggested, just slightly different. Add .ebextensions/python.config : container_commands: 03wsgipass: command: 'echo "WSGIPassAuthorization On" >> ../wsgi.conf' as explained at Using the AWS Elastic Beanstalk Python

阅读更多关于 View and Set HTTP headers for Safari/Chrome

问题 I'm testing an API and I would like to hit it with safari and see the raw json that's returned. The API requires a certain HTTP header be sent with every request. Is there a way in Safari or Chrome to set my http headers when visiting a URL? 回答1: There are a couple Google Chrome apps that do this. One is called Rest Console. I actually found an app called GraphicalHttpClient in the Mac AppStore that's a lot easier and more enjoyable to use. 回答2: Another popular chrome app for this is is

Removing the “Date” http response header on IIS 7+

阅读更多关于 Removing the “Date” http response header on IIS 7+

I am developing an ASP.NET Web API application which responds to the clients with a custom datetime http header. While I have read several articles describing how to remove response headers from ASP.NET/IIS, this one always seem to be resilient, i can't get rid of it. It seems to be placed in the response pipeline somewhere out of the programmer's/administrator's control, at the very end. I know it may be a bad practice not to include the "Date" header in the response but, as i mentioned, the custom datetime header (which is in ticks instead of a string representation) makes the default one

Django and dynamically generated images

阅读更多关于 Django and dynamically generated images

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 Content-Type:image/jpeg Date:Wed, 18 Aug 2010 15:36:16 GMT Last-Modified:Wed, 18 Aug 2010 15:36:16 GMT

ColdFusion - how to set Content-Length header

阅读更多关于 ColdFusion - how to set Content-Length header

Has anyone successfully added a Content-Length header to regular ColdFusion (I'm using CF9) pages? I'm setting up a new server behind a Cisco load balancer with compression - the box refuses to compress anything without this header, but CF doesn't pass it by default. <cfheader name="Content-Length" value="something"> will set the header, but finding the right value is a problem. Any pointers would be much appreciated. Geoff I believe I've solved it: <cfheader name="Content-Length" value="#getPageContext().getCFOutput().getBuffer().size()#"> I stuck that in o nRequestEnd() and the Cisco box is
