From: shapper on 18 Jun 2010 07:25 Hello, I am uploading a file on a Web Application which is a PDF document. However, for the content type I get "application/octet-stream" instead of "application/pdf". Do I need to install Adobe Acrobat Reader on the system so that a PDF file is recongnized? Thanks, Miguel

The question doesn't seem to be one of recognition but of configuration. But I can't tell you how without more specific information.

I am working on Windows 7 and I am debugging a web application. After some test I realized that when I upload a PDF file using IE the Content Type is "application/pdf". When using Firefox the content type is "application/octet-stream". The variable containing the file is a Stream. Isn't this strange? I mean shouldn't all mime types be available to all browsers on a system? Thanks, Miguel

It sounds like you shouldn't be relying on the browser to supply the correct MIME type but should instead either examine the file's extension or try to determine the file type by looking at the bytes. Preferably both.

You still haven't said how you are uploading the file (using an input tag with type="file"? some other means) or how you are determining what the content type is. > The variable containing the file is a Stream. > > Isn't this strange? > > I mean shouldn't all mime types be available to all browsers on a > system? Availability doesn't have anything to do with it. If a sender transmitting a stream or a recipient receiving a stream hasn't been told what the content type is, it has to make its own decision, correct? And two browsers by two different organizations aren't necessarily going to make the same decision. |
