Postback not work when using ReWriteUlr

[WK Steven Nguyen]

Hi,

I have use ReWriteUrl, but one problem:

This is real url: http://test.cityivm.com/AppWeb/eCms/Cuz/Ivm/Pages/Info/Home.aspx

And this is rewrite url: http://test.cityivm.com/Home

In config: 

<urlrewritingnet rewriteOnlyVirtualUrls="true" contextItemsPrefix="QueryString" defaultPage="Home" defaultProvider="RegEx" xmlns="http://www.urlrewriting.net/schemas/config/2006/07">

  <rewrites>

    <!-- Redirect Home -->

    <add name="RedirectApplication"

         virtualUrl="^~/Default.aspx"

         rewriteUrlParameter="ExcludeFromClientQueryString"

         destinationUrl="/Index.aspx" 

         redirect ="Application"

         redirectMode="Permanent"

         ignoreCase="true"/>

    <!-- Home -->

    <add name="Home" virtualUrl="^~/Home"

         rewriteUrlParameter="ExcludeFromClientQueryString"

         destinationUrl="/AppWeb/eCms/Cuz/Ivm/Pages/Info/Home.aspx"

         ignoreCase="true"/>

    

    <!-- Contact -->   

    <add name="Contact" virtualUrl="^~/Contact"

         rewriteUrlParameter="ExcludeFromClientQueryString"

         destinationUrl="/AppWeb/eCms/Cuz/Std/Pages/Info/Contact/Contact.aspx"

         ignoreCase="true"/>

  </rewrites>

</urlrewritingnet>

Problem is: i use 2 language and stored languageID in session, and use LinkButton to switsh language, LinkButton click event in code behind i save languageID to session and Redirect to file Index.aspx in root folder (Response.Redirect("/Index.aspx");). But if current page is http://test.cityivm.com/Home when i click change language then it not work (not change), but current page is another (ex: http://test.cityivm.com/Contact) then it work, i dont understand why. Postback does not seem to work in default home page.

Anyone help me, thanks.
