How can I validate that the file I have uploaded has right mime type if compared with the file extension?
I want to support all browsers. It means well that I must do the validation on the server. Or?
And how should I do?
Right now I use RadUpload and validates against the file extensions, it works well. But like I say I also want to make sure that the file extension matches the mine type.
Grateful for the tips!
Best regards,
