http-headers

问题 I have a requirement to implement a web-service that can issue files to the bits (Background Intelligent Transfer Service). The language is ASP.NET (C#). The problem I am having is with the "range" stuff. My code currently receives the http request (with a valid range is present in the http headers of 0 - 4907), and subsequently dishes out a portion of a byte array in the response object. Here's my server code: _context.Response.Clear(); _context.Response.AddHeader("Content-Range", "bytes " +

问题 I see a section called IANA Considerations in the RFC 6455 - Web Socket Protocol. It defines several HTTP headers to be added to HTTP protocol. Such as Sec-WebSocket-Key, Sec-WebSocket-Extensions, etc. But I didn't find these headers in the RFC 2616 - HTTP 1.1 Protocol. So are these headers definitions ready for use? (I am not quite familiar with how RFC documents are organized. So pardon me this is a dumb question.) 回答1: The HTTP protocol allows for custom headers to be added to any HTTP

问题 I have a Vanguard webservice which I can call (using basic authentication) using a custom java class. The java wsimport tool was used to generate the java proxy stubs and this all works perfectly. The java code (All classes below are generated by wsimport given a url + authentication info): Authenticator.setDefault(new SimpleAuth(username,pass)); MyWSObject obj = new MyWSObject(url); -> triggers the exception ServicePortType port = obj.getServicePort(); OutputType result = port.MyWSMethod

问题 If you are connected to the Internet directly (and not through a proxy) and requests for a page (get/post) in Internet Explorer 7, the default time-out is 1 minute. If the response from the web server takes more than a minute then you end up getting a "Network error" from IE. How can I increase this timeout in IE? Microsoft has documented How to change the default keep-alive time-out value in Internet Explorer, but this does not work in my PC (Windows XP SP2, IE 7.0). Does anyone out there

问题 I have a PHP application that I have been having some problems with, some pages take a very long time to load. After a couple of hours I have figured out the problem, but I have no idea how to fix it. The problem seems to be with the header Connection: keep-alive . I used a Firefox plugin called "Tamper Data" which allows you to "tamper" with the headers and stuff. Once I used that tool to change the connection header to Connection: close the delay on some pages stopped. How, in PHP, can I

问题 I'm making CORS requests between my web application and a server. The request is a simple authorization request. The request is sent, the server sets a "JSESSIONID" cookie, a dialogue box pops up, you type your username and password and then press submit. The httpRequest then completes once the credentials are correct, and the response header sets a "LWSSO_COOKIE_KEY" cookie for the client to use for access. The problem is that this is working flawlessly in internet explorer, and not in

问题 We have a multilanguage site and want to cache e.g. page /about . English and belarusian pages have the same URL: /about , language is stored in and detected from the cookies.

问题 I am using CORS for cross-domain talk on my website. Although, the response header as shown in the pic, seems fine to me, yet, I am not receiving any response. Its still blank or returns with response. Can anyone predict the error in my approach, seeing the attached image ?
