How can I block the link with the request?

Question

Apache HTTP Server

Good afternoon.
Task :
You need to make a redirect when you follow a link or
when you manually type a URL in the browser bar with a request like www.example.com?act=delete
There is such a rule in .htaccess that works

RewriteCond %{QUERY_STRING} act
RewriteRule (.*) http://www.example.com/? [R=302,L]

But there is a problem, there are forms on the page in which the same parameters are sent using the GET method, after which the data should be deleted. For example www.example.com?act=delete&id=1. And the request does not occur, because it immediately redirects to the main site
Question:
So, how to prohibit the transition to the url and allow the forms to send data?

Answer 1

This is VERY bad practice when data changes are made via GET. I can write right here in the comments

<img src="www.example.com/?act=delete&id=1">
<img src="www.example.com/?act=delete&id=2">
<img src="www.example.com/?act=delete&id=3">
<img src="www.example.com/?act=delete&id=4">
<img src="www.example.com/?act=delete&id=5">
<img src="www.example.com/?act=delete&id=6">
<img src="www.example.com/?act=delete&id=7">
<img src="www.example.com/?act=delete&id=8">

At the same time, YOUR browser with YOUR rights will make all these requests and delete everything to hell.

Answer 2

You can even without RewriteRule - it's easier to process on the site itself on the page.
