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.
The latter one allows you to write formatted output. Init () When the page is instantiated, Load() when the page is loaded into server memory; Pre Render() for the brief moment before the page is displayed to the user as HTML and Unload() when the page finishes loading. Are concurrent accesses by multiple requests executing on multiple threads a concern with session state?
If I update session state then should I lock it, too?
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.
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.
