Hello all,

please I need help with an a web app that I
am developing. I am using .NET 2.0, VS 2005, IIS 6.0, Windows Server
2003 Standard Edition sp2
The application was deployed our server in my country
and it was accessible over the internet from our clients.

Later due to QOS issues, we decided to host the app
on our dedicated server in the UK.

I re-deployed the app on the server via remote access means and
tested it out on the local machine using the hostname "localhost".
It worked but anytime I try to access it from over the internet from
another machine in
a different geographical location, the default.aspx page works,
displaying its content but the
main page (waspprovider.aspx) that sends data from the database as a
HttpResponse object,
doesn't display anything but the page gets hit.

The contents of the working Default.aspx page is as follows:

<%@ Page Language="C#" AutoEventWireup="true"
CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://
www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>Untitled Page</title>
</head>
<body>
<form id="form1" runat="server">
<div>
Welcome to Visafone web content provision web application.</
div>
</form>
</body>
</html>

The content of the waspprovider.aspx.cs page is as follows:

I wanted to add that the OS on the UK server is
Microsoft Server 2003 Standard edition Service Pack 2
and it has IIS 6.0 webserver running on it.

Thanks in anticipation of your response.

Regards,

Chike

Chike,
the ASP.NET group would be a more appropriate place to post your question.
This is the C# language group. Also, writing exception information to the
Console isn't going to help much in an ASP.NET web application!
