header header to indicate the source site information. Whether the value of the Access-control-allow-origin header needs to be matched with the origin information when the server responds. Header ("Access-control-allow-origin:http://localhost"); * For all domain names The disadvantage of cors is that you must be able to control server-side permissions, allowing you to access across domains Setting up cors to implement cross domain requests First,

Let's take a look at two ways to cross-domain submit form for PHP one, through the PHP curl function Curlpost ($url, $params){$postData = ';foreach ($params as $k => $v){$postData. = $k. ' = '. $v. ' ';}RTrim ($postData, ' ');$ch = Curl_init ();curl_setopt ($ch, Curlopt_url, $url);curl_setopt ($ch, curlopt_returntransfer,true);curl_setopt ($ch, Curlopt_header, false);curl_setopt ($ch, Curlopt_post, Count ($postData));curl_setopt ($ch, Curlopt_postfields, $postData);$output =curl_exec ($ch);Cu

Name is a global property of window, including ie6,7, which is supported by almost all browsers. Using Window.name to transfer data across domains is a feature of its use: Window.name has been saved even though the refresh, url jump The implementation principle is very simple, the homepage uses the IFRAME to load the Outland data page, the Outland page sets this iframe the Window.name value. After loading, the IFRAME jumps back to the blank page of

A simple example of how jquery uses Ajax to get data across domains var WebMethod = "Http://localhost:54473/Service1.asmx/HelloWorld"; JQuery.support.cors = true; Didn't add this sentence always hint no transport, I didn't go to deep thought. $.ajax ({ type: POST, contentType: "application/x-www-form-urlencoded", dataType: "html", URL: "http:/ /www.*****.com ",//Here is the URL success:function (da

Principles of DHCP authorization in Windows domains In a network of Windows, you can prevent illegal DHCP servers from being present by authorizing DHCP servers in domain mode. How does it work? A DHCP server running Windows Server 2003, which detects the availability of active Directory first during startup, and then determines whether to provide DHCP services externally: 1. For servers that are joined to a domain, the DHCP server queries the list of

Solution | browser | data Obtaining data from the same domain can be achieved by XMLHTTP components or IFRAME, and there are no permissions issues with Cross-domain access, so it is simpler.However, if you want to access data from different domains, because of browser security settings, XMLHTTP does not have access to the data, and the IFRAME does not have the right to pass the acquired data to the parent window, there seems to be no other solution.Ep

Introduction to bit domains in C LanguageWhen storing some information, it does not need to occupy a full byte, but only needs to occupy a few or one binary bit. For example, when storing a switch value, there are only two States: 0 and 1. Use one binary digit.To save storage space and simplify processing, the C language also provides a data structure called a bit field or bit segment. The bit field divides the binary character in a byte into several

. Parameters: The data returned by the server and processed according to the DataType parameter; A string describing the state. This is an Ajax event. Traditional Type: Boolean If you want to serialize the data in a traditional way, set it to true. Please refer to the Jquery.param method under the Tools category. Timeout Type: Number Sets the request time-out (in milliseconds). This setting overrides

cookie is not compressed, and the picture does not need to know the user's Cookie ,So this part of the bandwidth is wasted. When writing the master program, Set-cookie also do not set to the domain name of the picture.On small-traffic sites, this cookie doesn't actually save much bandwidth, and when it comes to Facebook Twitter, it saves a lot of money.About multi-domain, is not the more the better, although the server can do a pan-interpretation, the browser to do DNS interpretation is also ti

Applicationdomain------- A class of as3, or a technology or concept. Using this technology, you can easily call the server-side SWF and use the methods and variables in the SWF. Over the past few days, I have been more and more familiar with Flex communication technology, and feel that I am always using some surface applications. I am not familiar with how the entire virtual machine runs a SWF and some internal mechanisms. The language can be artificially encapsulated, but the user's freedom to

If a domain is not added, Windows cannot resolve the computer name in the domain to obtain the IP address. In particular, the XP Home Edition system cannot add domains. Sometimes, when you want to maintain your computer, you only know your computer name, but you do not know your own IP address. Remote Assistance may cause a little trouble. NSLookup, a powerful tool in the system, comes in handy at this time.As long as the domain DNS address is conf

Interpreting the implementation of the android Log Mechanism: (3) Writing Device Files in JNI and C/C ++ Domains Tian haili @ csdn Android provides a user-level lightweight Log Mechanism. Its implementation runs through Java, JNI, local C/C ++ implementation, Linux kernel driver, and Other Android layers, it is simple and clear enough to explain the case. This series of articles explains the internal implementation mechanism of the log mechanism. Th

I have been trying to talk about this problem for a long time. Many companies often use domain names to answer questions.
