Question

How would one display any add content from a ‘dynamic’ aspx page? Currently I am working on using the System.Web.HttpResponse ‘Page.Response’ to write a file that is stored on a web server to a web request.

This would allow people to hit a url to the type http://www.foo.com?Image=test.jpg and have the image display in their browser. So as you may know this revolves around the use of Response.ContentType.

By using

Response.ContentType = 'application/octet-stream'; 

I am able to display images of type gif/jpeg/png (all i have tested so far), bit trying to display .swf or .ico files gives me a nice little error.

using

Response.ContentType = 'application/x-shockwave-flash'; 

I can get flash files to play, but then the images are messed.

So how do i easily choose the contenttype?

This is ugly, but the best way is to look at the file and set the content type as appropriate:

switch ( fileExtension ) {     case 'pdf': Response.ContentType = 'application/pdf'; break;      case 'swf': Response.ContentType = 'application/x-shockwave-flash'; break;       case 'gif': Response.ContentType = 'image/gif'; break;      case 'jpeg': Response.ContentType = 'image/jpg'; break;      case 'jpg': Response.ContentType = 'image/jpg'; break;      case 'png': Response.ContentType = 'image/png'; break;       case 'mp4': Response.ContentType = 'video/mp4'; break;      case 'mpeg': Response.ContentType = 'video/mpeg'; break;      case 'mov': Response.ContentType = 'video/quicktime'; break;      case 'wmv':     case 'avi': Response.ContentType = 'video/x-ms-wmv'; break;       //and so on                default: Response.ContentType = 'application/octet-stream'; break;  }
