Security :: Limit Upload File Types?

Jun 14, 2010

I want to limit the allowed uploaded file types to images, pdfs, and docs. What is the recommended way to approach this?

I assume checking the file extension alone is not enough, since an attacked can change the file extension as he wishes.

This is basically for a course management system for students to upload assignments and teachers to download and view them.

AJAX :: File Upload With UpdatePanel Not Working. File Is Null. Updateprogress?

Jan 24, 2011

I'm trying to use below simple code for ajax postback. With file upload, neither javascript the "function startRequest" ever triggers, the file control shows null value somemore.Earlier I had Update progress which didn't work with file upload ever so I removed it. Now I just want to disable the button as the file is uploaded and its inputs are processed in the background. Once the response comes back, the "submit" button is re-enabled.But the file-upload with Updatepanel doesn't work at all. What am I doing wrong,
