Fails on uploading favicon.ico

[kade-robertson]

When uploading a file named favicon.ico to transfer.sh through the website, you get a bunch of garbled mess (I believe it's the data for your favicon) instead of a link to the upload.

This is presumably because it makes a PUT request to https://transfer.sh/favicon.ico which isn't/shouldn't be allowed. This is on Chrome 73.0.3683.86 on Mac OS 10.14.3:

When uploading using curl it's not quite as bad, since you receive a warning:

$ curl --upload-file ./favicon.ico https://transfer.sh/favicon.ico
Warning: Binary output can mess up your terminal. Use "--output -" to tell
Warning: curl to output it to your terminal anyway, or consider "--output
Warning: <FILE>" to save to a file.

And if you follow the warning, you get:

$ curl --upload-file ./favicon.ico https://transfer.sh/favicon.ico --output -
K�(K������������������������������������¼�ý�þ�þ��������Ý� ... # goes on

Which ends up being your favicon (as suspected):

There should probably be some kind of warning if uploading a file that's invalid (or some way to handle this special case, i.e. not serving your favicon on a PUT if that's possible).

I will fix limiting http.FileServer handler only for GET requests. Anyway it is unlikely to see the fix on http://transfer.sh :)
