web.config prevents file downloadable or viewable <p>I am very new to ASP.net. I visited a website long time ago which I cannot remember the URL now. I wanted to open their CSS file to see the source, but once I clicked the error message says, "you don't have premission to act ........."</p> <p>Now I want to do the same thing to lock up my files. Even visitors could see the file name, but they are unable to open or download it.</p> <p>I wonder if it is possible to achieve on ASP.net or IIS7?</p> <p>Many thanks for suggestions.</p>
