Re: downloading a zip file attachment

Hi Mark,

you can export ZIP files like this - given that you have a zip file on disk:

(http:define-url-export-type :zip-file :zip (:application :zip) :copy-mode :binary)

(http:export-url #u"/test.zip" :zip-file
                 :pathname #p"/Users/joswig/Desktop/my-test-zip-file.zip")  ; example pathname


Does that help?


Best regards,

Rainer
