I would like to ask about the right format for a POST request when it is NOT a collection of parameters and their corresponding values but just a single string (just a value without the parameter)?
Should it be POST=somestring or POST==somestring? I tried both but it does not work.
For an easier approach, open the online page with the link (form) you want to download in the Internal browser. Click the link or form submit button with the Alt+Ctrl keys pressed and you will get a new Project with the URL, Referer and POST requests entered in the URLs field.
