Hi Oliver,
Instead of using HTTP for upload/download (which requires more pieces
and more complex senttings) I would recommend you to use directly SIP
for transporting CPL scripts (via REGISTER). CPLEd supprts also this method.
In order to separated normal REGISTERs from CPL transport REGISTERS,
From the SER part you must do something like:
if (method=="REGISTER") {
if ( cpl_process_register() ) {
sl_send_reply("500","Error");
};
# here you can do normal processing of a
# REGISTER request or whatever you want
};
In CPLEd, in the upload/download window you have to fill in the address
and port of SER and the user name for which you want to install/fetch
the script.
Regards,
Bogdan
