How to submit a form without Javascript and not by pressing any buttons?

How can we submit a form without Javascript and not by pressing any buttons?
I need to transfer a content to another file when a function works under
certain conditions. Both the files are written in Perl. The pages are
loaded in a webserver(same). I need to transfer a value, which the user
doesn't want to know what I'm sending. So I came up with the post method
is safe.
But there I didn't find any ways to redirect a URL where the values are
transmitted in post method. So I came up with the form submission. But the
problem is I need to use javascript or make user to press a button to
complete the task.
The problem with Js is there some users who disable JS in their browsers.
So using it is not preferable. With the button, I can't make the user to
do that for me.
Is there any other scripting language, which supports such functionality?
