httpwebrequest problems

[Tyler]

I am using httpwebrequest to do a screen scrape.

This works great on my development box, but does not on the production box.

Here is the code.

Dim webRequest As HttpWebRequest = CType(webReques t.Create(LOGIN_ URL),
HttpWebRequest)
webRequest.Prox y = System.Net.Glob alProxySelectio n.GetEmptyWebPr oxy
webRequest.Keep Alive = False
Dim responseReader As StreamReader = New
StreamReader(we bRequest.GetRes ponse.GetRespon seStream)
Dim responseData As String = responseReader. ReadToEnd
responseReader. Close()

On my production box, I get this error:
The underlying connection was closed. Unable to connect to the remote server.

I have made sure I have .NET framework 1.1 SP 1 installed

I have added the following code to my web.config file

<system.net>
<defaultProxy >
<proxy
usesystemdefaul t = "false"
proxyaddress="h ttp://proxy:port"
bypassonlocal=" false"
/>
</defaultProxy>
</system.net>

And now I am at a loss?

Any thoughts?
Thanks

Um,
don't you want GetDefaultProxy , not
webRequest.Prox y = System.Net.Glob alProxySelectio n.GetEmptyWebPr oxy

Its' DefaultProxy that you show in your config. You can also try more
specific code like this:

if (ConfigurationS ettings.AppSett ings["proxy"] != null)
{
WebProxy p = null;
string proxyAddressAnd Port =
ConfigurationSe ttings.AppSetti ngs["proxy"];
string proxyUserName =
ConfigurationSe ttings.AppSetti ngs["proxyUserN ame"];
string proxyPassword =
ConfigurationSe ttings.AppSetti ngs["proxyPassw ord"];
ICredentials cred;
cred = new NetworkCredenti al(proxyUserNam e, proxyPassword);
p = new WebProxy(proxyA ddressAndPort, true, null, cred);
GlobalProxySele ction.Select = p;
}

Thanks for your response Peter. I tried both suggestions with the same
result. This one has me baffled. I can type the url into a browser on the
production box and it will pull up the site just fine. And again, it works
on my development box, but not the production box.
