I tried putting the following in my cl-http response function:
(http:with-successful-response (stream '(application octet-stream) =
:additional-headers '(:content-disposition "attachment;filename=3D\"My =
Text File.txt\""))
=20
but the browser gave me the error:
Internal Server Error
Required arguments in "attachment;filename=3D\"My Text File.txt\"" don't =
match lambda list (HTTP::DISPOSITION . HTTP::PARAM-PLIST).
CL-HTTP/70.216 (Clozure Common Lisp; 0.9.91)
I assume I gave the wrong format for the :content-disposition header; do =
you know what the correct one is?
Thanks,
Mark
