NET that tests user input in HTML and Web server controls for programmer-defined requirements. Concurrent accesses aren't an issue with session state, for two reasons.
NET user control is authored declaratively and persisted as a text file with an extension. NET page framework compiles a user control on the fly to a class that derives from the System. It's up to you to prevent this from happening by using an encrypted communications channel (HTTPS). In addition, you must use the IIS configuration applet to enable localhost (127.0.0.1) to relay messages through the local SMTP service. VSDISCO files are DISCO files that support dynamic discovery of Web services. Do they, for example, include the client's IP address or anything else that would distinguish the real client from an attacker? If an authentication cookie is stolen then it can be used by an attacker. NET just before it shipped, you need to set Smtp Mail's Smtp Server property to "localhost" even though "localhost" is the default. If the user is working with a browser that supports DHTML then the validation controls can also perform validation using a client script. Session state is locked down when the Http Application instance that's processing the request fires an Acquire Request State event and unlocked when it fires a Release Request State event. NET forms authentication cookies provide any protection against replay attacks? Validation controls perform input checking in server code. One, it's unlikely that two requests from the same user will overlap. NET locks down session state during request processing so that two threads can't touch it at once.In this article you will learn collection of numerous . Introduction Most of the questions and answers you likely have already read. Asp Compat is an aid in migrating ASP pages to ASPX pages. Net Framework questions and answers for which a reader must normally look around the entire internet in various community web sites. What does Asp Compat="true" mean and when should I use it?
The purpose of this article is to consolidate most of the study material related to . It defaults to false but should be set to true in any ASPX file that creates apartment-threaded COM objects; that is, COM objects registered with Threading Model=Apartment.
In this example, it prevents caching of a Web page that shows the current time.
Just call Set No Store on the Http Cache Policy object exposed through the Response object's Cache property, as demonstrated here: Set No Store works by returning a Cache-Controll; a private, no-store header in the HTTP response.
Persistent authentication cookies do not time-out and therefore are a more serious security threat if stolen. Note that VSDISCO files are disabled in the release version of ASP. You can reenable them by uncommenting the line in the section of Machine.config that maps *.vsdisco to System. Is it possible to prevent a browser from caching an ASPX page?
NET can detect when a form is requested for the first time versus when the form is posted (sent to the server), that allows you to program accordingly. Custom controls A control authored by a user or a third-party software vendor that does not belong to the . This is a generic term that includes user controls. So a stolen session cookie can only be used in replay attacks as long as the ticket inside the cookie is valid. You can change that by modifying the timeout attribute accompanying the element in the Machine.config or a local Web.config file. Mail Message and Smtp Mail are classes defined in the . A client who requests a VSDISCO file gets back what appears to be a static DISCO document. However, Microsoft is actively discouraging the use of VSDISCO files because they could represent a threat to Web server security.
A custom client control is used in Windows Forms applications. NET: A user-authored server control that enables an ASP. Authentication cookies issued as session cookies, do, however, include a time-out valid that limits their lifetime. If you place the following VSDISCO file in a directory on your Web server, for example then it returns references to all ASMX and DISCO files in the host directory and any subdirectories not noted in How does dynamic discovery work? NET maps the file name extension VSDISCO to an HTTP handler that scans the host directory and subdirectories for ASMX and DISCO files and returns a dynamically generated DISCO document. Discovery Request Handler and granting the ASPNET user account permission to read the IIS metabase.
