Custom Button posting login

[pfellner]

How can I create a custom button so that it "posts" login info for a script such as an admin panel?

if script accepts GET parameters you may just specify them in URL like:
http://domain.tld/script?username=user&password=password
However, it is rather unsafe way if requests are submitted over non-encrypted connection.

No, it does not accept the "get" method.

then the only way is to create some script on some location (either where target application located or somewhere else) which will accept GET parameters, form a request and redirect user to the target application.
