From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux 2.2.17-21mdk i686; en-US; 0.8) Gecko/20010215
BuildID:    0.8 release

For a dynamically page (generated from CGI/PHP/JSP..), hitting RELOAD will cause
the loss the of the variables.

Reproducible: Always
Steps to Reproduce:
I have created a test case, in http://chip.uhome.net/mozilla_bugs/reload/page1.html

1.Fire up MOzilla, goto the URL above;
2.Try to enter some information, then submit the form, PHP will assembly a page
called page2.php.
3.On the next page (page2.php), you can see the values are transferred;
4.Hit "Reload", the values are disappeared.

Actual Results:  All values is lost.

Expected Results:  the value of the variables should be kept.

This bug won't occur when using the following browsers in Linux (Mandrake 7.2):
- Opera 5.0b6;
- Netscape 4.75
- Lynx 2.8.4dev.8 (24 Aug 2000)

Also, I've checked it against IE 5.0 Under win98, the problem also won't occur.

The HTML code if page1.html can be obtained simply by viewing source code;

Here are the code of page2.php (very simple one):

  <title>Mozilla bug test: form variables page 2</title>
  $hidden_var1 = <? echo($hidden_var1); ?><br />
  $hidden_var2 = <? echo($hidden_var2); ?><br />
  $text_var1 = <? echo($text_var1); ?><br />
  $text_var2 = <? echo($text_var2); ?><br />

Also, the win32 build of 0.8 also suffers by this problem.

I have another example that doesn't involve a RELOAD, but the POST vars are 
nuked anyway:


Try sending a file (for example:  /etc/profile and then hit the SEND File
button)  I enabled debug statements to show the post variables, and they are
all gone.  This page works fine on other browsers.  The PHP source is visible at

Let me know if I should submit a separate bug report for this problem.  The loss
of POST variables is a really bad problem -- I would mark up the severity of
this problem...

I have a case where doing a RELOAD actually fixes some posting problem.
The first time I do a post, some data is wrong or missing.  But if
I back up to the form and make the same changes to the form and post
again, it works, usually.  Sometimes just reloading the form the 
first time I visit it fixes the problem, sometimes not.  

If this sounds like a useful clue, I can probably narrow it down further by
getting debugging info from the server about what was actually posted.

if i do reload the page may be reloaded from cache but the post data is still
there, if i do shift-reload i get a popup warning me it will resend post data.
