I'm writing a C# application for .NET 2.0 in which I intend a number of
background worker threads to be conveying information from our SQL Server
database to a legacy database via HTTP GET requests. Each worker thread
runs the following code in a loop:
-----
HttpWebRequest request = (HttpWebRequest)WebRequest.Create([snip]);
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader responseReader = new StreamReader(responseStream);
string responseText = String.Empty;
string line;
while ((line = responseReader.ReadLine()) != null)
{
if (line != String.Empty)
responseText += line;
}
responseReader.Close();
response.Close();
-----
The total number of requests will end up being approximately 30,000 for each
run of the transfer, so I'm trying to run as many threads as I can so the
total run time will be reduced. But it appears that .NET by default
restricts the number of simultaneous network connections to a single host to
2 (why?!). I did find that if I create an application configuration file
that looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<system.net>
<connectionManagement>
<add address = "10.134.0.2" maxconnection = "24" />
<add address = "*" maxconnection = "2" />
</connectionManagement>
</system.net>
</configuration>
I should be able to have up to 24 connections to that 10.134.0.2 host (see
http://support.microsoft.com/kb/821268/en-us).
However, this isn't working--I still seem to be constrained to two
connections. Any suggestions as to what I might be doing wrong? The
application name is RightsTransferToADAMS.exe and I have a
RightsTransferToADAMS.exe.config file in the same directory with the content
above. Is there a way to programmatically check that the config file has
been loaded correctly and that I should be able to make 24 connections? Do
I need to do something else?
Thanks very much for any help you might be able to provide.
