On my php server I have a list of urls that point to large files (not locally stored). These files can be hundreds of Mb so I'm looking for the best way to add them to GCS without first saving them to my server. Is this possible or will I have to save each one then upload it to GCS?
Edit
I forgot to mention the list of urls that I have is managed programatically and changes often so any solution needs to be able to be implemented without manual interaction.
