HTTP Range Request Tester
Test whether a file host supports HTTP Range requests (partial content delivery).
Range support is required for resumable downloads and parallel chunk transfers.
Why These Tools Exist
When transferring large files to Google Drive, understanding your source URL is critical. An incorrect or malformed URL will fail partway through. A source that doesn't support Range requests cannot be resumed if the connection drops. Knowing the file size in advance lets you verify you have enough Drive storage. These tools help you inspect and validate before you transfer.
