Description:
------------
After posting (method POST) a form (of any kind) the $_POST variable does not get populated. This error is hard to reproduce as it occurs sporadicily but sometimes more than once on the same form. Apparently with under the same conditions it sometimes works and sometimes not.

I experience the problem (I believe) only using SSL. I'm using rewrite rules, but the same as on other sites without SSL.

I read stuff about mentioning the action property in the form tag, about GPC order, etc... but nothing I've tried can reduce the error to it's origin. I do not know however how to check apache for incoming POSTed data.

Apache:
Server      Version:      Apache/1.3.27     (Unix)     (Red-Hat/Linux)
   FrontPage/5.0.2.2623     mod_ssl/2.8.12    OpenSSL/0.9.6b    PHP/4.3.4
   mod_perl/1.26 mod_python/2.7.6 Python/1.5.2 mod_webapp/1.2.0-dev
   Server Built: Dec 21 2003 12:00:54

Can you recommend me some actions ? I have not found any relevant info on the web.

See bug #18648 and check your httpd.conf ...

Obviously you are not using Apache2, so

Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz

For Windows:

  http://snaps.php.net/win32/php4-win32-STABLE-
latest.zip

my httpd.conf only mentions:

AddType application/x-httpd-php .php4 .php3 .phtml .php
AddType application/x-httpd-php-source .phps

However I have found a key to the origin: apparently the values I enter in the form influence the problem. I have been able to reproduce but cannot figure out any logic. I have to mention I'm only using a-zA-Z and - signs..
it's like black magic...

I have not yet installed the snapshot, will definitely await final release. I have to mention as well that I just upgraded to 4.3.4 from 4.3.2 where the problem occured as well.

Just try the snapshot first.

I will wait for the definite release. I can however allready add these comments:

- only occurs on SSL
- occurs when some fields (no reserved words as names) have spaces, numeric values, and perhaps others.

In the meantime I moved to just HTTP instead of HTTPS

Can not reproduce using latest CVS (or even with 4.3.4)

I don't beleive this is a PHP bug.  We started receiving similar problem reports at the university I work for after the latest Internet Explorer security update was released.  I came across the following Microsoft Knowledge Base article yesterday and the software update linked under the "Resolution" section appears to fix the problem:

http://support.microsoft.com/default.aspx?scid=kb;en-us;831167

I wasted 2 full days tracking down something that looks very similar to this. In my case it's limited to IE and SSL only. Very intermitant. What solved it for us was this:
http://support.microsoft.com/default.aspx?scid=kb;en-us;831167

and adding 
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown
to our apache config in the ssl enabled virtualhost section. Give it a shot and see if it works for you too.

Thanks, I should have thought as much :)

Closing the issue

Since it wasn't a bug in PHP, it should be set to bogus.
