Best Pattern for AllowUnsafeUpdates

Question

So far, in my research I have seen that it is unwise to set AllowUnsafeUpdates on GET request operation to avoid cross site scripting. But, if it is required to allow this,

Answer 1

Another clean way to implement would be to use a combination of extension methods and anonymous delegates as such:

public static void DoUnsafeUpdate(this SPWeb web, Action action)
{
    bool allowUnsafeUpdates = web.AllowUnsafeUpdates;
    web.AllowUnsafeUpdates = true;
    action();
    web.AllowUnsafeUpdates = allowUnsafeUpdates;
}

Using the above extension method, you can then perform your "unsafe update" action as follows:

var web = SPContext.Current.Web;
web.DoUnsafeUpdate(delegate()
{
    // Put your "unsafe update" code here
});
