How can I use IIS to test my pages in VS.NET, and not use the internal server?
|
| |
In the Solution Explorer, right-click the name of the Web site for which you
want to specify a Web server, and then click Property Pages.
In the Property Pages dialog box, click the Start Options tab.
Under Server, click Use custom server.
In the Base URL box, type the URL that Visual Web Developer
should start when running the current Web site. You can use localhost.
From that point on, the VS.NET IDE will not use the internal web server,
but will use IIS to open your pages, i.e., if you are working on default.aspx,
it will be opened as : http://localhost/default.aspx
