Redirect to another site after login is not working

Question

We have an already running asp.net web site (lets call it example.com). In our new site (mostly HTML pages) we call login page from old site using thickbox like following:

<a href="http://example.com/login.aspx?keepThis=true&TB_iframe=true&" 
             class="thickbox">login</a>

login.aspx is a simple page with two fields (id, pwd) and a login button. On login button's handler following code is run after validating the credentials:

response.Write("<script type='text/javascript'> 
         top.location.href='example.com/usermain.aspx'</script>");

On clicking login link it successfully loads login.aspx page in thickbox., but after logging in (clicking login button) in IE 8 it always redirect to http://example.com/index.aspx which is default home page for site (for guest/anonym visitrs). If I am using Firefox it properly redirects to http://example.com/usermain.aspx most of the times.

Please help me find out what I am doing wrong.

请改用window.location.assign(url) 。
