I'm not sure if this is the right place to ask, but I'll try my luck I have a question related to hiding a POST request:

1) user inserts his/hers email in to a email form on a website and clicks "continue"
2) the email will be embedded in to the POST request and the POST request launches
3) I don't want the end user to see the content of the POST request. I don't want the end user to be able to manipulate the POST request, as it has parameters that I don't want to be manipulated.

Is it some way possible to restrict this/hide this information from the user? If anyone knows about this, or knows to where should I look at, I would highly appreciate it!
