Firefox & reloading page: keeps unsubmitted value for select

Question

I have a page that contains a select element for creating a new object.

When a user visits the page, if he/she selects a value from the select element and then reloads the page (using cmd|ctrl + R) the select keeps the value even though the value was never submitted.

I don't want the option to be remembered upon reloading since it was never submitted.

I tried adding in my application controller a before filter in order to disable cache:

before_filter :disable_cache

def disable_cache
  expires_now
end

Using a browser tool (HttpFox) I get the response header:

Cache-control no-cache, private

and the response body has no selected option in it but while rendering, user's selected option before the reloading of the page is still there.

Response body:

<select class="select optional" id="an_id" name="a_name">
  <option value=""></option>
  <option value="1">a</option>
  <option value="2">b</option>
  <option value="3">c</option>
</select>

An actual reset for the select happens only when using cmd|ctrl + shift + r

Any ideas?

No, nothing selected. I will provide the response body on my original post in a minute. — Lazarus Lazaridis, May 20 '13 at 15:13
Can you add the "selected" attribute to your `value=""` option? I don't know much about ruby-on-rails, but I'd think that would fix it. — eidsonator, May 20 '13 at 15:20
@eidsonator Nope, not an option since this will default to the "" value even if the user **has submitted another value**. — Lazarus Lazaridis, May 20 '13 at 15:24
Workaround: I had to disable autocomplete. From [here][1] [1]: http://stackoverflow.com/questions/2486474/preventing-firefox-from-remembering-the-input-value-on-refresh-with-meta-tag — Lazarus Lazaridis, May 20 '13 at 20:16

Workaround: I had to disable autocomplete.

Either on specific element or the the hole form.

I found the solution from here
