Description: ------------ If the WebDAV server sends a 401 Authorization required response to an OPTIONS request from MS MiniRedir (Microsoft-WebDAV-MiniRedir/5.1.2600), the client gives up and hands over the connection the other client in Win XP, (Microsoft Data Access Internet Publishing Provider Cache Manager). Using MiniRedir is usually preferred over the other client. An OPTIONS request doesn't reveal much information about the system, so I don't think it would be a big problem if OPTIONS request didn't ask for authorization. The behaviour can be changed achieved by changing the line if (!$this->_check_auth()) { in ServeRequest() to something like if ($_SERVER['REQUEST_METHOD'] != 'OPTIONS' && !$this->_check_auth()) {

Summary changed (my browser's auto-fill function filled out the field)

For now i have disabled auth checking for the webdav root directory only (code is in CVS) so that OPTION can't be used as a tool for path guessing without authentication does that already fix your problem?

Hello, I encountered a problem today with Dreamweaver CS3, related to this bug. Apparently, DW issues an OPTIONS request and then a PROPFIND request. If the OPTIONS request doesn't return a 401 response and PROPFIND does, DW aborts the entire communication.<br> <br> The issue is fixed in Dreamweaver CS4, however I suggest you replace the fix in Server.php with a test specific for the MiniRedir client:<br> <br> if ( ( !((stristr($_SERVER['USER_AGENT'], 'Microsoft-WebDAV-MiniRedir') && $this->_SERVER['REQUEST_METHOD'] == 'OPTIONS') && ($this->path == "/")))<br> && (!$this->_check_auth())) {<br> ...<br> }<br> <br> The fix worked for me on all tested clients (I used the built in WebDAV clients in XP, Vista and MacOS, as well as Dreamweaver and BitKinex).
