I can zip the addons, that's easy.
I can send a HHTP request as well.

But I don't know how to script the upload. Can you explain me the url to:
- log me in
- upload an addon

Thanks!

you need to go where you installed the files on your server.. for me this was my /Uni/ folder. To access it, the link would be http://www.yoursite.com/unifoldername/

so mine is http://www.dr-guild.com/Uni/

Once logged in, go to Addon Management

Scoll down and you will see some boxes. Click the browse button and find the file on your computer.

Fill in the version number manually by typing the numbers in.. remember the dots.

For home page, I usually put in http://wowroster.net

when done, click add / update addon.

This will initiate the file upload. To make sure the other person gets it, they must make sure that when syncing, they are updating their add-ons.

Hope I answered all your questions.

Thanks for your response, but I wasn't precise enough.
I want to script (in dos) the upload of addons. So I want to put in a shell a request as for example (this comes from my imagination): http://mywebsite/uniuploader/upload.php ... athToAddon\Addon.zip?Username=user?password=pass
But I haven't found in the php code the relevant parameters (I'm surelly too silly for that)

this can't be so hard to not have any answer -_-'

The fields you need to pass values for are

name
password

required (1 for required addon, 0 for optional)
file (this is the posted file)
version
homepage
