Hello all,

we have an application that makes requests to an IIS server using XMLHttpRequest.

We're trying to call 2 ASP pages simultaneously using 2 asynchronous XMLHttpRequest from the client-side.

For some reason, IIS refuses to execute both pages simultaneously. Both requests are processed one after the other.

However, if we start 2 browsers, we can make simultaneous calls (one call from each browser).

We already know that it's not the browser that blocks the second call. Looking at the IIS log, we saw that IIS receives both request simultaneously but processes them one after the other.

Is this an IIS setting? Can we change it?

Thanks in advance,
Alex
