Disk2vhd is a utility that creates VHD (Virtual Hard Disk - Microsoft's Virtual Machine disk format) versions of physical disks for use in Microsoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). The difference between Disk2vhd and other physical-to-virtual tools is that you can run Disk2vhd on a system that's online.

Visual Subst is a small tool that allows you to associate the most accessed directories with virtual drives. It uses the same API similar to the console 'subst' utility, but makes it easier to create and remove virtual drives in a GUI way.

"Load Testing a Virtual Web Application"

The Sitecore Users' Virtual Group is dedicated to supporting the Sitecore community wherever they exist across the globe. We're excited to announce a monthly education series on Sitecore topics. We have some great speakers lined up for our first sessions, and we're looking forward to their deep expertise on Sitecore development. All sessions are free of charge and conducted over the web.

Web Performance Load Tester is a powerful and easy to use tool that will allow you to automate load testing and generate reports to help you analyze the performance of a web site. The 10 virtual user version, which is full featured, is free to use and is ideal for identifying pages that exceed a threshold value for further investigation.

"Viewstate (ASP.NET) ASP.NET has an option to maintain your ViewState. The ViewState indicates the status of a page when submitted to the server. The status is defined through a hidden field placed on each page with a control. Viewstate can be used as a CSRF defense, as it is difficult for an attacker to forge a valid Viewstate. It is not impossible to forge a valid Viewstate since it is feasible that parameter values could be obtained or guessed by the attacker. However, if the current session ID is added to the ViewState, it then makes each Viewstate unique, and thus immune to CSRF. To use the ViewStateUserKey property within the Viewstate to protect against spoofed post backs. Add the following in the OnInit virtual method of the Page-derived class (This property must be set in the Page.Init event) protected override OnInit(EventArgs e) { base.OnInit(e); if (User.Identity.IsAuthenticated) ViewStateUserKey = Session.SessionID; } The following keys the Viewstate to an individual using a unique value of your choice. (Page.ViewStateUserKey) This must be applied in Page_Init because the key has to be provided to ASP.NET before Viewstate is loaded. This option has been available since ASP.NET 1.1. However, there are limitations on this mechanism. Such as, ViewState MACs are only checked on POSTback, so any other application requests not using postbacks will happily allow CSRF. "
