Http
An HttpData resource specifies a list of objects on the web to be transferred over HTTP. The information of the objects to be transferred is contained in a file referenced by a URL. The first line in the file must be "TsvHttpData-1.0", which specifies the format of the file. Subsequent lines specify the information of the list of objects, one object per list entry. Each entry has the following tab-delimited fields: * HTTP URL — The location of the object. * Length — The size of the object in bytes. * MD5 — The base64-encoded MD5 hash of the object. For an example of a valid TSV file, see Transferring data from URLs. When transferring data based on a URL list, keep the following in mind: * When an object located at http(s)://hostname:port/ is transferred to a data sink, the name of the object at the data sink is /. * If the specified size of an object does not match the actual size of the object fetched, the object is not transferred. * If the specified MD5 does not match the MD5 computed from the transferred bytes, the object transfer fails. * Ensure that each URL you specify is publicly accessible. For example, in Cloud Storage you can share an object publicly (/storage/docs/cloud-console#_sharingdata) and get a link to it. * Storage Transfer Service obeys robots.txt rules and requires the source HTTP server to support Range requests and to return a Content-Length header in each response. * ObjectConditions have no effect when filtering objects to transfer.
