do need configure on http server or script/programm should running on server upload file server ?
could 1 please ?
you need cgi script process data @ /repo or /repo/proc.out
the cgi script should written in language supported web server environment.
the script read environment, , data sent script, process it, , send response curl script.
some web servers come default cgi script dump data you. might found in cgi-bin directory.
