Previously, we have briefly introduced how to use Jquery in MVC, because we must understand Jquery if Ajax is used. This blog will give a general introduction to ASP. net mvc: How to Use Ajax as an auxiliary method. This blog is my reading notes. If it is not well written, ask your friends to come up and learn it together.1. Preparations(1) At the beginning of MVC learning, we need to introduce

View status management is a simple and convenient technology. Through view status management, control developers can simulate stateful and seemingly continuous execution in an originally stateless environment. The specific process is: Whenever a user requests a. aspx page, the. NET Framework first serializes the status of the related control into a string, and then uses it as a hidden domain named _ VIEWSTATEThe Value is sent to the client. If the pag

Store security information to the Registry and configuration file Controls the access permissions of remote users to the configuration file to protect sensitive data in the configuration file. 7. modify the configuration file before publishing To prevent misstack information speculation and attack by other means of information discovery,

applications can be found in almost all the _ viewstate hidden fields on HTML pages. Because _ viewstate is base64-encoded, it is often ignored. However, hackers can easily decode the Base 64 data and get the details provided by _ viewstate without any effort.■ Risk AnalysisBy default, __viewstate data will include:(1) Dynamic Data from page controls.(2) The data explicitly stored by the developer in viewstate.(3) Signature of the password for the ab

system, which corresponds to some requests of the client and then makes some specific response actions, but it does not have the ability to capture client events. Therefore, it is impossible to directly communicate ActiveX controls with ASP. NET Server applications.Therefore, based on my experience, we can select two methods for implementation. First, we can wri

control and deal with these anomalies, perhaps I say a lot of people will associate with the try{}catch{}, it is true that the exception of the capture is with them, but you have not thought, if a website is flooded with try{} catch{}, not only not beautiful, but also to control. and ASP . NET MVC provides us with an exception filter that allows you to add this

ASP. NET development (Interface Guide ), After a public platform user submits information, the server sends a GET request to the URL filled in with four parameters: The developer verifies the request by verifying signature (The following is a verification method ). If you confirm that the GET request is from the server, the echostr parameter is returned as is, a

ASP. NET (C #)-connect JAVA to RSA encrypted signatures-Lecture 3, asp.net In this chapter, let's take a look at how Java implements RSA encryption. Ah? Why? If you want to compare the differences, you have to see how people encrypt them. Previously, I only talked about how to implement RSA encryption and decryption and signature verification in C #. Java only t

ASP and net interview questions 1. Briefly describe the access permissions of private, protected, public, and internal modifiers.A. Private: Private Members can be accessed within the class.Protected: protects members, which can be accessed within the class and in the inheritance class.Public: A Public member. It is completely public and has no access restrictions.Internal: accessible within the same name

scenario is described, we will analyze it. Although intuition tells the coders that there may be a problem with reading or writing cookies, intuition is unreliable. We still need to talk about facts and evidence. In international practice, capture an HTTP packet first: It is the HTTP Response Header returned by the server when the server fails to log on to IE10. It is the HTTP Response Header returned by the server when other browsers log on normall

On the ASP. NET webpage, use the server button. By default, the first button responds to the button clicking event. Most of the time, the first button is not something the user wants to do after clicking enter. Generally, the Enter key is used to submit data after the input is completed, for example, close the current pop-up window, enter a keyword, and press enter to search. The solution for setting the En

ASP. NET 1.1 introduces the ability to automatically check the existence of XSS (Cross-Site Scripting) for submitted forms.

not disable validaterequest = false for programmers who wish to handle this error message well without using the default ASP. NET exception message. The correct method is to add the page_error () function on your current page to capture exceptions that occur while processing all pages without handling them. Then, the user is given a valid error message. If the c

This paper is a processing model based on IIS6.What happens when a client page accesses IIS trying to get some information? What happens when a request passes through the HTTP pipeline? This article mainly describes these two processes, that is, IIS processes ASP. NET requests and the page life cycle of ASP.First, we need to figure out two very important concepts:1, worker process (w3wp.exe). The worker pro
