PHP referrer problem

[supercain]

Hi,

im using this string to get the referrer to my page

$_SERVER['HTTP_REFERER'];

i use it on an application form to see whats the referrer of the applicants and i get it on my mail address along with all the info sent by the applicants. However, in some cases the referrer appears as the same application form page! example: my application form is domain.com/form.php and referrer shows as domain.com/form.php too. Is that possible? in which cases can this happen?

Thank you.

In some cases or all cases?

$_SERVER HTTP Referer should show where the recent user just came from, but

- In cases where someone accesses your page directly.

REFRESHDATA has to repost the information if someone has hit refresh on a page.

- In cases where the page is posting to itself.

Thanks, but if someone access directly (by typing the URL on the address bar) then nothing should appear. I have tested it and nothing ever appears as referrer in those cases. Is that the only case it happens?
