Rajganesh,

May be I was not clear in explaining my issue.

Links you have provided are showing how to add references of a external dll to asp.net applications I create in visual studiol

Here is the issue I am facing.

Under IIS WebSites we have Default Web Site. I have created External Web Site under WebSites with a different IP.

There are virtual directories under both the Default and External web site. I have to apply a custom HTTPModule to only Default Web Site.

If the user access any virtual directory under Default web site the modules kicks in.

If the user access any virtual directory under External web site module shoud not do anything.

So I thought may be this HTTPModule can be configured at the WebSite level instead for each virtual directory.

I created a config file under Default Web Site root folder where I have provided configuration for the HTTPModule.

When I a hit virutal directory URL from browser its trying to load Module but failing with the exception I have sent earlier.

 Sorry for the confusion created.

Thanks

Sai Prasad
