Hi,

We have a asp.net web application in which we are making HTTP requests to a
remote
web server (CGI) & get response in form of XML data. We are using
HttpWebRequest
object to post the request. In case of concurrent users using our web
application:
1. On a page if there are multiple such HTTP requests, will IIS process the
requests
synchronously or asynchronously?
2. For concurrent users, will IIS use multiple threads to process the
requests
simultaneously?
We are using IIS6 on Windows 2003. Is there a setting to control this
behaviour?

Thanks in advance.

by default, there are 2 simultaneous requests per connection. The rest will
be queued irrespective of synchonicity. The setting can be configured in the
config file.

IIS is able to service requests asynchronously be default.

ASP.NET services users from a threadpool which implies concurrency
