remove host header vulnerability using url rewrite

Hi,

 

My website name is : "http://abcportal.uk.in/xyz_Portal/_layouts/login.aspx"

 

My code in web config is: 

 

<rewrite>

  <rules>
<rule name="Remove Host Header" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTP_HOST}" pattern=".*abcportal.uk\.in" />
<add input="{HTTP_HOST}" pattern="www\.abcportal.uk\.in" negate="true" />
</conditions>
<action type="Redirect" url="http://abcportal.uk..in/{R:1}" redirectType="Permanent" />
</rule>
</rules>

</rewrite>

 

But when I call "http://abcportal.uk.in/xyz_Portal/_layouts/login.aspx" it redirects to "http://abcportal.uk.in/"

 

Please help
