It may seem like this has been asked before, but I have a wrinkle to this question.
I have a Mosso / RackSpace Cloud site that I am trying to redirect inbound PDF requests such as site.com/abc.pdf to a pdf handler page that will serve them up from App_Data via a BinaryWrite.
They have a sample at http://www.wip.rackspacecloud.com/knowledge_center/index.php/How_do_I_rewrite_URLs_from_ASP.NET that shows how to do this, I have tried it and it does not serve files UNLESS the original file exists.
I am being told by Mosso / RackSpace Cloud that file redirection only occurs when the original file exists.
Does the original file need to exist for a rewrite (as shown in the example) to work?
Local testing under IIS Express 7.5 says not. Perhaps Mosso have the pipeline configured odd somehow so that IIS runs first. I think I am being fobbed off.
