Just noticed how the data browser creates folders - nothing about “slug” or “link” headers here. It simply creates an empty “.dummy” file under the folder name and leave it to the server to create the folder itself:
PUT https://elfisk.solid.community/public/solidrc/.dummy HTTP/1.1
Host: elfisk.solid.community
Content-Length: 0
Origin: https://elfisk.solid.community
Accept: */*
Referer: https://elfisk.solid.community/public/
Accept-Encoding: gzip, deflate, br
Accept-Language: da-DK,da;q=0.9,en-US;q=0.8,en;q=0.7,sv;q=0.6,nb;q=0.5
DNT: 1
and then deletes it again:
DELETE https://elfisk.solid.community/public/solidrc/.dummy HTTP/1.1
