Malformed http header

[Michael Mangeng]

Hi   I�m using the apache httpd as a proxy between the internet and apache-tomcat which serves dynamic pages.   For my vhost i�m using proxypass / http://localhost:8081/webapp proxypassreverse / http://localhost:8081/webapp   all works find and the pages get served as long as i do not access pages which use informations stored in the appropriate session.. if i work only with apache tomcat i get the following line in the http header:   Cookie: JSESSIONID=F291F12ABC86D02A8DE252ED67969218 which, as you surly all know, maps the user to his session..   but if i request the pages throught apache with mod_proxy this cookie line is simply MISSING in the http header which reaches tomcat.   I do not know if the sessionid is filtered out from the http header on the way to the client or on the way to the server.   So my question: what can i do that the correct sessionid can be exchanged between the client and the server apache tomcat) ?   thans for your help greetings mike
