#38094 [Com]: Custom 404 doesnt receive POST variables

ID: 38094 Comment by: dangos at gmail dot com Reported By: mdcore at gmail dot com Status: Open Bug Type: IIS related Operating System: 2003 PHP Version: 5.1.4 New Comment: I have confimed this issue, and it _is_ a PHP bug. When presented with an HTTP POST through an IIS 6 custom error handler, PHP receives the raw POST data into php://input, but fails to parse it into $_POST etc. For comparison, ASP scripts do receive POST variables from IIS 6 custom error handlers, whereas PHP scripts do not. PHP also mangles $_SERVER['QUERY_STRING'] and $_GET and incorrectly reports $_SERVER['REQUEST_METHOD'] as 'GET' in this situation. I can suggest that the likely reason for the above problems is that when presenting a custom error to a script ISAPI filter IIS6 prepends the error status code to the beginning of the URL (e.g. 404;http://www.example.com/) - this odd format is possibly causing confusion when PHP attempts to process the server variables.

I think it is a bug in the PHP ISAPI filter because if I use a custom 404 ASP page then the POST variables do come through. It's only with PHP pages that it does not work. ------------------------------------------------------------------------ [2006-07-13 12:53:30] tony2001@php.net It clearly DOES pass them, as you said it yourself: >this works in IIS5 but not in IIS6. Please report it to Microsoft. ------------------------------------------------------------------------ [2006-07-13 12:47:44] mdcore at gmail dot com Why is the PHP ISAPI filter not passing the POST variables to the script? ------------------------------------------------------------------------ [2006-07-13 12:43:19] tony2001@php.net Sorry, but your problem does not imply a bug in PHP itself.
