Custom Login

I'm trying to add a custom login for ISP on my website. I used the following code which I got from ISP's login.php file:

Code:

<form method="POST" action="login/login.php" name="loginForm"> 
<table width="100%" height="100%" border="0" cellpadding="0" cellspacing="0"> 
  <tr> 
    <td align="center" valign="middle"><table width="400" border="0" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"> 
      <tr> 
        <td><img src="design/default/images/login_logo.png" width="398" height="78"></td> 
      </tr> 
      <tr> 
        <td bgcolor="#FFFFFF"><table width="100%" border="0" cellspacing="0" cellpadding="5"> 
          <tr align="center"> 
            <td height="66" colspan="2" class="normal"> 
                        Here you can log in:                        </td> 
            </tr> 
          <tr> 
            <td width="35%" align="left" class="normal">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Username:</td> 
            <td width="65%"><input type="text" name="username" class="text"></td> 
          </tr> 
          <tr> 
            <td align="left" class="normal">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Password:</td> 
            <td><input type="password" name="passwort" class="text"></td> 
          </tr> 
          <tr> 
            <td>&nbsp;</td> 
            <td><input type="submit" name="B1" value="  Login  " class="button"></td> 
          </tr> 
          <tr> 
            <td>&nbsp;</td> 
            <td>&nbsp;</td> 
          </tr> 
        </table></td> 
      </tr> 
    </table> 
      <p>&nbsp;</p></td> 
  </tr> 
</table> 
</form> 

the only thing I changed was:

Code:

<form method="POST" action="login/login.php" name="loginForm">

to

Code:

<form method="POST" action="http://cp.g3-services.com:81/login/login.php" name="loginForm">

The problem is after I click "submit" it takes me to the ISP login page, but it dosent log me in. Any suggestions?

Thanks

okay I tried that, it still does the same thing...

so scratch that idea from my website

 

Full domains or different hosts in the same domain?

I've never seen an issue with firefox submitting something viewed eihter with the file:// protocol or http://localhost to a different domain...

 

I've tried with IE, Firefox & Google chrome..

The domains are hosted on the same server though
