I have written an ASP.NET app that searches an XML database
for journal titles.  The app passes two session variables
(title and means of search) from one page to another.  I
only now got the session variables to work as intended.

The problem started when I press the Search command
control on my default.aspx page.  The appropriate code
is here:

private void cmdSeek_Click(object sender, System.EventArgs e)
{
   Utility Util = new Utility();
   if (Util.IsValidSearchPhrase(this.txtSeek.Text))
   {
       string resultsURL;

       Session["sought"] = (string) this.txtSeek.Text;
       Session["sortby"] = (string) this.rdoSortby.Selection.Value;

       resultsURL = this.ResolveUrl("results.aspx");
       this.RedirectToMobilePage(resultsURL);
   }
}

Now, the command control works as intended on browsers that access
the page via wired (IE, Netscape) or Wi-Fi (PocketIE, Palm/NetForce)
connections.  The control does *not* work on cell phone browsers like
OpenWave or BlackBerry.  I found out why on examining the ASP.NET
output to the OpenWave browser:  ASP.NET is interpreting the URL
as going back to default.aspx!

<anchor title="Seek">Search
   <go href="/ ... /Default.aspx">
       <postfield name="__EVENTTARGET" value="cmdSeek" />
       <postfield name="txtSeek" value="$(txtSeek)" />
       <postfield name="rdoSortby" value="$(rdoSortby)" />
   </go>
</anchor>

Is there any way to make ASP.NET interpreting the URL correctly?
