The Sametime Connect for browsers client and Sametime Links applications<br />

may not function appropriately with other JVMs, including the native Microsoft<br />

VM provided for Internet Explorer.<br />

Restriction: The Sametime Connect for the desktop client (that is, the<br />

Microsoft Windows version of Sametime Connect) cannot be used with a<br />

Sametime server that is deployed behind a reverse proxy server.<br />

Server limitations<br />

The following limitations apply to Sametime server features when the Sametime<br />

server is deployed behind a reverse proxy server.<br />

► Audio/video is not available - Audio/video streams cannot be transmitted to<br />

Sametime clients that access the Sametime server through a reverse proxy<br />

server.<br />

► TeamRoom and Discussion databases are not available - A user that<br />

connects to the Sametime server through a reverse proxy server cannot use<br />

the TeamRoom and Discussion databases on the Sametime server.<br />

► Access to the Sametime Administration Tool is not available - A user that<br />

connects to the Sametime server through a reverse proxy server cannot<br />

access the Sametime Administration Tool. The user can open a Web browser<br />

that is installed on the Sametime server to access the Sametime<br />

Administration Tool. The user can also connect to the Sametime server from<br />

an internal network location that does not route HTTP traffic through the<br />

reverse proxy server to access the Sametime Administration Tool.<br />

► Sametime Enterprise Meeting Server restrictions - The Sametime 1.0<br />

Enterprise Meeting Server that operates with Sametime 3.1 servers cannot<br />

be deployed behind a reverse proxy server<br />

5.5.4 SSL and client certification considerations and issues<br />

Secure Sockets Layer (SSL) can be used to encrypt data transmitted between<br />

the Sametime clients and the reverse proxy server. However, SSL cannot be<br />

used to encrypt data transmitted between the Sametime servers and the reverse<br />

proxy server. Thus, the connection between the reverse proxy and the Sametime<br />

server should be secure.<br />

Tip: If SSL is used to encrypt data transmitted between Web browsers and the<br />

reverse proxy server, the administrator must perform the mapping<br />

configurations on the Sametime server necessary to map the HTTPS data<br />

received from the Web browser to the HTTP required by the Sametime server.<br />
