/*
when running on VS development server i can access all paths of all elements on page,
such as "link" path "App_Themes/LayOut.css" or "img" path "Slike/someimage.jpg" and of course main url 
of page "one/two/three" to rewrite it to "Default.aspx?arg1=one&arg2=two&arg3=three"
*/

/*
when i run page on local IIS i can access only main url (context_BeginRequest fires only one time)
so i can rewirte only main url, but i can't rewrite my css, javascript, images and other 
stuffs paths...
