Hi, I use Delegated 8.9.4 on our Firewall to 'proxy' http to an internal IIS with Outlook Web Access. This works fine for a Mozilla browser (client), but with Internet Explorer 6.x I do not get the icons on the left side, neither do I get the checkboxes in front of every message in my INBOX because communication stops... When I 'bypass' delegated with 'port forwarding', it works !. So delegated must do something with it. Via the logging I noticed that IE uses 'http SEARCH', and Mozilla not, but I have already added SEARCH to my HTTPCONF. The strange thing is that is 'has' worked until a few weeks ago. I suspect that some M$ code was 'automagically upgraded', but I can not find any ref to it. I have also tried other IIS + OWA installations and it is the same. My Conf: DGROOT=/var/spool/delegated ADMIN=root@able..be -P10.0.0.2:80 SERVER=http://192.168.32.1:80 REMITTABLE=http PERMIT="http:192.168.32.1:*" HTTPCONF=methods:'+,SEARCH,PUT,DELETE,PROPFIND,PROPPATCH,MKCOL,COPY,MOVE,LOCK,UNLOCK' Note: between the Internet and our Firewall is a 10.0.0.x subnet (NAT), so that's why there is -P10.0.0.2:80 Part of the log, just before the communication stops : (and below a similar part with Mozilla as browser) Any help is largely appriciated Thanks alex ..... 05/19 16:30:38.95 [7104] 1+2/2/3: No-Cache to reuse 05/19 16:30:38.95 [7104] 1+2/2/3: #HT11 SERVER ver[HTTP/1.1] conn[] 05/19 16:30:38.95 [7104] 1+2/2/3: #HT11 server KEEP-ALIVE 05/19 16:30:38.95 [7104] 1+2/2/3: HTTP/1.1 304 Content-{Type:text/xml Encoding:[/] Leng:0} Server:Microsoft-IIS/5.0 05/19 16:30:38.95 [7104] 1+2/2/3: HTTP transmitted: 266head+0/0body=>0txt+0bin->0/0, 9i/0o/0f/0.0 05/19 16:30:38.97 [7104] 1+2/2/3: #HT11 putServ(10/15) 192.168.32.1:80 05/19 16:30:39.18 [7105] 2+1/1: ClosedOnTimeout(0): time=1084977039/1084977067 ppid=7103/7103 pid=7105/7105 05/19 16:30:39.18 [7105] 2+1/1: Proxy: host=gwb.able.be;
