<p>I'm trying to unit test a piece of code that needs a currently logged in user in the test. Using the .Net 2.0 Membership Provider, how can I programmatically log in as a user for this test?</p>
| <pre><code>if(Membership.ValidateUser("user1",P@ssw0rd))
{
FormsAuthentication.SetAuthCookie("user1",true);
}
</code></pre>
| <p>Using your Membership Provider you can validate a user using Membership.ValidateUser. Then you can set the authentication cookie using FormsAuthentication.SetAuthCookie. As long as you have a cookie container this should allow you to log in a user. </p>

<p>I am doing 2^1000 and I am getting this:</p>

| <p>That depends on how much noise you have on your motor power supply ground. You definitely want the 100 µF capacitor to have a good high frequency response. Motors turning on and off can be noisy, and that noise can cause false clock signals in your logic circuitry if you tie the grounds together. </p>

<p>I have ASP.NET web pages for which I want to build automated tests (using WatiN & MBUnit). How do I start the ASP.Net Development Server from my code? I do not want to use IIS.</p>

Start Process Explorer while debugging your website. For VS2012, expand 'devenv.exe' node. Right-click on 'WebDev.WebServer20.exe' and from there you can see Path and Command Line values.</p>

<p>Is there a way to have a RewriteRule fire on any domain that is requested on a box? For example, I have 5 VirtualHosts that would have the exact same RewriteRule applied to them and currently each VirtualHost directive has the rule, but can I put this somewhere 'global' so that upkeep is easier?</p>
| <p>No, I'm afraid not</p>
| <p>You can, but it is somewhat of a hack.
Create your RewriteRule in a .htaccess somewhere like:</p>
<blockquote>
<p>/www/redirects/global/.htaccess</p>
</blockquote>
<p>Now just set the DocumentRoot for your virtualhosts to /www/redirects/global/ and every request will be forced through your RewriteRule's.</p>
