Data from "multipart/form-data" goes missing

(Sorry if this is a duplicate post; I sent it through the news server but began to think that might not be forwarding posts to the list) For some reason, on just one server, data from forms posted with ENCTYPE="multipart/form-data" never makes it to the PHP script. We use this extremely simple test script: <form method="post" enctype="multipart/form-data" action="<?= $PHP_SELF ?>"> <!--<form method="post" action="<?= $PHP_SELF ?>">--> <input name="textbox"> <input type="submit"> </form> <pre> <?= var_dump($_REQUEST) ?><hr><?= $GLOBALS['CONTENT_LENGTH'] ?> </pre> And on this one server, no output shows unless the first <form> tag is commented and the second uncommented. On all other servers, with apparently identical configuration, form data appears normally. In all cases the Content_Length value rises and falls with the length of the string I type into the text box. The build on this server (PHP 4.1.2) is extremely simple: ./configure --with-apache=../apache_1.2.23 --with-mysql Apache is built with PHP and mod_rewrite. Any ideas? miguel
