Board index » delphi » Using TidHTTP in multi-threaded application

From my desktop application, I am generating x number of threads (using
delphi TThread class). Each thread is calling a local CGI by using the Indy
TidHTTP component. Each CGI sends a SOAP request to an external machine
(with public IP address) and get a response back. The thread then writes the
response back to the main thread (desktop applicaiton). This is working just
fine.
If the main thread (desktop application) generates 10 threads, I can see by
looking at the Windows Task Manager (Performance tab) that 10 threads are
gernerated. I can also see that 10 CGIs are executing in the Windows Task
Manager (Processes tab).
Now, if for example, the main thread creates 50 threads, Windows Task
Manager (Performance tab) shows that 50 threads are created but the Windows
Task Manager (Processes tab) only shows 10 threads at a time. After few
observations I found that IIS 5.0 restricting the number of HTTP calls at
one given time. My first question here is that can I increase that limit???
Now, if the main thread creates 100 threads, all threads are created as
normal but for 20 of those threads throw an error like "Socket Error # 10061
Connection refused". So my second question is that why I am getting this
error even though the IIS is managing the number of threads at one given
time.
Thanks in advance.

In the IIS manager. Unless you are running the server edition of the
windows OS, you will be limited on the number of concurrent connections.
it's allowable limit.
 

I am using the Windows 2000 Server edition where there is no limit for a
number of connections. So how come I am still getting the connection refused
error?
