Example: Http.ResumeDownload method

Demonstrates the ResumeDownload method. Lua

-- To demonstrate resuming a download, we've created a file on the chilkatsoft.com
-- web server that contains the first 82,379 bytes of the full  279,658 bytes of the hamlet.xml file.

-- We'll first download the partial file, and pretend it was a previous incomplete attempt to download the entire file.
local localFilePath = "c:/temp/qa_output/hamlet.xml"
local success = http:download("https://www.chilkatsoft.com/testData/hamlet_partial.xml", localFilePath)

-- Download the remainder of hamlet.xml.
