I have a site running of www.mysite.com for example.

There is a JS file I'm accessing: www.mysite.com/packages.js

The first and subsequent times that I acccess that packages.js file causes no problems........until I access a sub-site like this:

sub-site.mysite.com

This naturally makes a request for that same packages.js....but the site hangs as it just keeps waiting and waiting for that JS file.

Going back to the main site, the problem perists there.

If I then rename packages.js to say packages2.js it then works in the same way. I can access the file on the main site but after I try and access it through a sub-site IIS then fails to respond to a request for that file.

I realise this explanation is a little vague, but has anyone seen this sort of behaviour before?

Thanks very much,

James.
