WampServer

I'm a senior web developer and i used to work using the wamp for long time, but i faced recently a sudden problem.

I install a fresh copy of wamp 2.0h on a new computer XP SP2, it worked correctly for one month, but now when i try to POST something, it posted twice so each record entered the DB twice and even if i try to upload file, it's been uploaded twice.

i restarted the wamp, it worked fine for a little time then the problem occurred again.
i tried to uninstall it and reinstall again, the same problem is still here.

I notice by accident that this problem occurs only for large files and in firefox only.

thank you in advance for your help.

Hi,

Problem is not from Wamp.
it depends of how browsers manage $_POST and header...

You can use some tips to avoid it.
- Add a $_SESSION['already_post'] for example

<?php
if (isset($_SESSION['already_post'])) echo 'Can\'t submit twice';
else {
   $result = mysql_query("INSERT INTO ...";
   $_SESSION['already_post']=1;
}
?>

- Use an intermediate page.
I often use a page which control datas, do query then go back to the first page..
