My web page does not have the autocomplete attribute that would tell browsers not to autocomplete the field. In spite of not having this attribute, IE 8 or Safari (not sure on other browsers) does not autocomplete the page.

Autocomplete does work on some sites (such as Gmail) so I am assuming that the browser setting is not causing it?

Here's the code:

      <tr>
        <td>User Id</td>
        <td><input name="userId" type="text" id="userId" runat="server" /></td>
      </tr>
      <tr>
        <td>Password</td>
        <td><input name="password" type="password" id="password" enableviewstate="false" runat="server" /></td>
      </tr>
