we're successfully rewriting URLs (Helicon ISAPI_Rewrite) to classic ASP pages. We then decided to apply similar rules for ASP.NET pages. However, all we get back are 403 errors. Directly calling the .net pages returns pages fine!
Are we missing a setting? The server is Windows 2003 running in IIS6 mode.
solved it. It was to do with the fact that the .net code was in a virtual directory where it was running in the .net application pool. The rewriten URL was "outside" the viritual directory (in root of site) - this was running in the default application pool. I just changed it to the .net pool and hey presto Bob's your uncle!
