Asp.net does not allow you to have multiple html FORM tags on the same page, sort of.

The reason for this is Asp.net uses the FORM tag with the runat="server" attribute to process the form.

You could create a second form outside the FORM tags with the runat="server" attribute, but Asp.net will not process the second form.

The problem is, this may not be what you want. If you have an email sign up form or a buy now button, you may want the multiple forms inside the Asp.net FORM tags.

There are a few techniques you can use to accomplish this.

1. Use an IFRAME and include your FORM in the IFRAME.
2. Use the Asp:Button PostBackUrl property.
   
   <asp:Button
     ID="Button1"
     PostBackUrl=http://www.domain.com/handleform.aspx"
     Runat="server"
     Text="Send" />
   
3. Use client side redirection.
   
   <input type="button" value="Send"
   onClick="location.href='http://www.domain.com/handleform.aspx">
