Sometimes existing folders are not found and creation fails

[fkalis]

This is a follow-up to #12.

Sometimes it happens, that the folder traversel does not return the id of an existing folder. Therefore the script tries to create the folder and fails because the folder does already exist.

The folder traversel should rely on HTTP status codes instead of curl return codes.

Idea:

Simultanous retrieval of status code and content with curl:

curl -w "%{http_code}" -o >(cat >&1) 'http://example.com' 2>/dev/null | tail -n 1
curl -qfsw "%{http_code}" 'http://example.com' | tail -n1
curl -w "###HTTP_CODE###: %{http_code}\n" -o >(cat >&1) 'http://example.com' 2>/dev/null | grep "^###HTTP_CODE###: " | cut -d\  -f2
curl -qfsw "\n###HTTP_CODE###:%{http_code}" 'http://example.com' | grep "^###HTTP_CODE###:" | cut -d: -f2

and

curl -w "%{http_code}" -o >(cat >&1) 'http://example.com' 2>/dev/null | head -n-1
curl -qfsw "%{http_code}" 'http://example.com' | head -n-1
curl -w "###HTTP_CODE###: %{http_code}\n" -o >(cat >&1) 'http://example.com' 2>/dev/null | grep -v "^###HTTP_CODE###: "
curl -qfsw "\n###HTTP_CODE###:%{http_code}" 'http://example.com' | grep -v "^###HTTP_CODE###:"

Warning: head -n-1 does not work under OS X, using grep seems to be the most compatible solution.

This behaviour is reproducible with special characters (e.g. German Umlauts).

Closed until I see this happen again.
