ApplicationHost and HttpModule problem

V

Vlad Losev

I am trying to execute a web page in application host (without IIS) using
ApplicationHost, but have a ConfigurationException thrown. I have several
HttpModule add directives in Web.config but cannot remove them, it would
cripple my application). I wonder if there is any way to get rid of this
error?

[ConfigurationException]: The module 'CommerceApplication' is already in the
application and cannot be added again (C:\Inetpub\wwwroot\dotnet\web.config
line 80)
at System.Web.Configuration.HttpConfigurationRecord.Evaluate(String
configKey, SectionRecord section)

configKey, Boolean cacheResult)

configKey)

Here is a section of my web.config that describes the http modules:

string aspDir = HttpRuntime.AspInstallDirectory;
string domainId =

execept for debugging

}

static void Main(string[] args)
{
MyExeHost myHost =
(MyExeHost)CreateApplicationHost(typeof(MyExeHost),"/",Directory.GetCurrentD
irectory());
myHost.ProcessRequest("app.aspx");
}
}

Vlad,

I'm afraid I don't know the solution to your problem, but I can tell you
that I've seen the same thing while working with the Cassini web server from
http://asp.net/. In my case, I was able to remove the offending items from
web.config for testing purposes, so I haven't come up with a solution, or
even a diagnosis. Sorry.
