Sequence for running the codes of the links

Two click codes are associated with the links:

a browser click code, entered in WLanguage (or in Javascript) in the code editor. This code is included in the HTML page and it will be run on the computer of Web user.
a server click code, entered in WLanguage only. This code will be run on the server.
