As an example, I'm currently uploading items directly to an S3 bucket using a form. While I was testing, I didn't specify any expected filenames or extensions.
I uploaded a .png which produced this direct link:
When I place this inside an img tag, it displays on a web page properly.
My question is, without an extension, how would my browser know what type of file it's loading? Inside the bucket, the file's metadata isn't even filled out.
Is there any way to get that file extension, programmatically?
I'm ready to try any clientside methods available; my server-side language is ColdFusion which is somewhat limiting, but I'm open to suggestions for that as well.
