in file when use print_r( $_session ) it's right.

this problem i've seen while doing flex, upload through flash seems not use cookies (and loses sessions). if uploadify uses flash problem.

you might fix setting token identifying user , instead of uploading http://example.com/upload.php ought upload http://example.com/upload.php?token=azpodkazpoj1dzapdo (you upload script has implement mechanism find , check user token.

edit : suggested in suspected duplicate question, can use session_id token

java - Need to add SOAP security token -

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
