I have installed openstack swift 2.25.2

object-server writes and serves local files from disk

It receives http requests from a proxy-server, for example:

http get: /sdb4/525/AUTH_xxxxxxxxxxxxxxxxxxxxxxxx/panda/2c34a941f581d848e2799e7a0956ea14f3cb27b0e516aef99a438fdaebbd7592

reads a file from disk:

/srv/node/sdb4/objects/525/346/835ee70dce07217d8e33147e0864f346/1643910916.71556.data

how can I calculate the path by which the file will be read by object-server?

thanks
