Could anyone point me the direction how I can implement uploading

CGI the only way to accomplish it? There are lots of materials on how

Here's an exmple on how to do it with portableaserve http://

(publish :path "/getfile-old"

:function #'(lambda (req ent) (getfile-function
req ent "/getfile-got-old")))

(publish :path "/getfile"
:content-type "text/html; charset=utf-8"
:function #'(lambda (req ent) (getfile-function
req ent "/getfile-got")))


(defun getfile-function (req ent posturl)
(with-http-response (req ent)
(with-http-body (req ent)
(html (:head "get file")
(:body
((:form :enctype "multipart/form-data"
:method "post"
:action posturl)
"Let me know what file to grab"
:br
((:input :type "file"
:name "thefile"
:value "*.txt"))
:br
((:input :type "text" :name "textthing"))
"Enter some text"
:br
((:input :type "checkbox" :name "checkone"))
"check box one"
:br
((:input :type "checkbox" :name "checktwo"))
"check box two"
:br
((:input :type "submit"))))))))




Any suggestions are welcome!
