HP StoreAll Storage - Manual (Page 223)

This example downloads an existing file called xyz.jpg in the lab/images subdirectory of the
ibrix_share1
HTTP share. The file is created with the filename a1.jpg on the client system, in
the subdirectory temp of the user’s current directory.
If the file already exists at that path on the client, its contents are overwritten by the contents of
xyz.jpg
, provided that the local client’s permissions and retention settings on that file and directory
allow it. If the overwriting is denied, a local client system-specific error message is returned.
Delete a file
This command removes a file from the StoreAll file system by using the HTTP share interface. File
deletion is subject to StoreAll permissions on the file and directory, and it is subject to retention
settings on that file system. If file deletion is denied, an HTTP error is returned. If the file does not
exist, a 404 Not Found HTTP error is returned.
NOTE: The delete command is only for WebDAV enabled shares.
The HTTP command is sent in the form of an HTTP DELETE request.
HTTP syntax
The HTTP request line format is:
DELETE // HTTP/1.1
[Sync-Requested: 1]
The equivalent curl command format is:
curl -X DELETE http[s]://://
--header [Sync-Requested: 1]
The optional "Sync-Requested: 1" header is about durability. After the requested change has been
made to the file, a sync is done to ensure that the change has been made durably on disk before
the HTTP response is sent to the user. Note that this operation will wait all buffers be flushed to the
disks before return back the operation result. If this header is requested, the HTTP response will
return a header "Sync-Result" header. The value which follows that key represent the errno value,
where 0 (zero) means that sync was done successfully and any other value indicates sync does
not complete and durability is not guaranteed.
See “Using HTTP” (page 174) for information about the IP address, port, and URL path.
Description Parameter
