Good afternoon person, I'm breaking my head here and could not find a solution. What I need is this.

If a user accesses a url by ex: www.site.com.br/produto it should be redirected to another page with a login type ex: www.site.com/login .

If he is logged in he wanted the user to be redirected to the previous page, however adding the following parameter at the end of the URL: ?id=CS In the example I would then give: www.site.com.br/produto?id=CS

window.location.href = '/?id=CS';

The above code redirects only to the home page, but wanted it to go back to the previous page it tried to access.

Using the document.referrer you have access to the previous page. But remember this command uses the browser information so if you've been redirected from Google.com > your site it will return to Google.com?id=CS

if(window.location.href.indexOf("?id=CS") == -1) {
   window.location.href = document.referrer+'?id=CS';

}
else{
   //não faça nada 
}
