By default one user can open only one simultaneous connection on IIS6, how to increase this number? I do not find any option in IIS6 for this.

IIS doesn't limit the number of users, but the apps it runs might. Which application framework?

I've noticed ASP and possibly ASP.Net behave that way when you're using Sessions - if you disable ASP's session support, you can create multiple requests to the same page, unserialized.

As far as I know there is no such limit in IIS - the limit is on the browser side. For example, IE7 and Firefox 2 (by default) limit you to 2 simultaneous connections, IE8 and Firefox 3 to 6 simultaneous.

If you are seeing a limit of 1, then this was probably customized at some point. See this Microsoft KB article about IE, and this setting for Firefox.
