Is public search form vulnerable to DDOS attack?

Question

I have a typical search form as one of the main functions. As it is a public one, I am scared of getting DDOS attacked.

The only way I think of to avoid it is to:

1. I will use a method="post" form with token on it.

2. When the user/attacker submit the form.

3. I will check if the button is clicked and if the token is correct.

4. If both true, I will reload the page along with the search value. ex www.url.com/?q=search_value

Will this prevent the DDOS attack?

Answer 1

In short: No. Why should it? Even if you just have a static single page site, you are susceptible to DDOS attacks that might consist of nothing more then repeated requests for that single page ...
