RE: [PHP] Page not displayed/Forbidden on PHP forms

I would check the follwing: - If the problematic host has apache's mod_security enabled. The system administrator can tell you if mod_security is disallowing some of the input (which might cause the "403 forbidden"). - PHP.INI parameters max_execution_time, max_input_time and max_input_nesting_level (more info is at the online php manual) you can query these values through ini_get, and you can set them through ..htaccess files, e.g. "php_value max_execution_time 300" (if the hosting company allows their use). - Call ignore_user_abort at the top of the processing script (CAREFULLY read the notes for that function) and query the value returned by connection_status, or connection_aborted (maybe create a log file for the returnded values through successive requests to keep track of any issue) - Check what (cache) headers the server or your processing script is sending to the browser. - Also, if $_REQUEST processing is a time consuming operation and you use ob_start, ob_end_flush, etc you can try flushing the output buffer from time to time (if your programming logic allows for that). Well, this is quite a list... but if they are getting "403 forbidden" it might be an issue with the server configuration (such as a highly restricted mod_security configuration), rather than server performance or speed. Hope that helps. Ohh, by the way, if you can send the culprit URL to us for testing it will help a lot (BUT DON'T DO THAT if this is a private system, or a system for which you don't want to get any additional traffic).
