The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

How to keep Web Server alive during task that runs up to 9 minutes

Zones: Scripting Languages, JavaScript, Dynamic HTML (DHTML)

Tags: iis 6.0, vb2005, asp.net 2.0, Javascript, Ajax, ie 6, system.web.httpexception: request timed out

I am trying to keep the web server alive while I update from very few to up to 20,000 or 30,000 rows. My boss wants to reduce backend requests to our server ops group. This update is limited to our field support group.
===================================================================================
I have tried running it as an async call.
Dim async_Transfer_Data_Delegate As New Transfer_Data_Delegate(AddressOf Transfer_Data)
Dim asyncResults As IAsyncResult = async_Transfer_Data_Delegate.BeginInvoke(Nothing, Nothing)
Do Until asyncResults.IsCompleted
Thread.Sleep(5000)
Loop
Dim strResults2 As String = async_Transfer_Data_Delegate.EndInvoke(asyncResults)
Me.lblMessages.Text &= strResults2
The async call finishes, but the web server still times out.
===================================================================================
I have tried using Javascript to call in an image.
function Reconnect() {
count++;
if (count = 1) {
window.setInterval('Reconnect()', interval);
}
if (count < max) {
var img = new Image(1,1);
img.src = 'KeepAlive.aspx';
var d = new Date();
}
else {
window.clearInterval();
}
}
Where my image is an aspx page.

<%@ OutputCache Location="None" VaryByParam="None" %>
<!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><title></title></head>
<body></body>
</html>
The javascript executes. I have used alerts to watch the progress. The web server still times out.
