Very strange URL rewrite problem?

Question

I am rewriting the url http://www.tworiverstaines.co.uk to http://www.tworiverstaines.co.uk/TwoRivers/

When the site first loads the rewrite works correctly displaying Default.aspx with all the hyperlinks working correctly including the path to the App_Themes folder etc.

However when you click on the homepage link (or any other) when the Default.aspx (or page requested) loads all the hyperlinks and paths are altered from /Default.aspx to /TwoRivers/Default.aspx so when you click on a hyperlink it is broken as the rewrite rule will take you to www.tworiverstaines.co.uk/TwoRivers/TwoRivers/Default.aspx.

To prevent the 404 error I have added a local rule to rewrite /TwoRivers/TwoRivers/ to /TwoRivers/ however this isn't a good solution as the URL in the browser shows the subfolder and pages become available at /Default.aspx and /TwoRivers/Default.aspx which could present duplicate content issues with search engines.

Does anyone have any idea why this is happening?

The site can be accessed at http://www.tworiverstaines.co.uk

I am displaying the header information at the bottom of each page to display the paths.

Answer 1

This is because of your action attribute in your form tag. Do you rewrite that form tag also?

On the Page http://www.tworiverstaines.co.uk/Default.aspx you action attribute contains

<form name="aspnetForm" method="post" action="TwoRivers/Default.aspx" id="aspnetForm">

if not, here is a solution:
