Uploading large files with HTTP_Request class

Hello, I need to perform uploading of large files using the HTTP_Request class: http://pear.php.net/manual/package.http.http-request.php I am *not* using this one: http://php.net/manual/en/class.httprequest.php The HTTP_Request class support the following functions: setBody() and addFile() The addFile()-function however simulates a form field and the server application does not read the incoming file from such a field. I have to put the file content as a stream through the body. Adding the file content using the setBody()-function will of course cause an out of memory error: $fp = fopen($filename, 'r'); $request->setBody(fread($fp, $filesize($filename))); $fclose($fp); $response = $request->sendRequest(); How am I supposed to do that with this class? Are there any alternatives, which do not force me to add new PHP dependancies/libraries to the project? I am writing a library and do not want to force the users to add dependancies to their projects in order to use this library. I am currently using PHP 5.3.0. Thank you and best regards, Marko ------------------------------------------------------- Fachinformationszentrum Karlsruhe, Gesellschaft für wissenschaftlich-technische Information mbH.
