5.5.5 Mapping rules on the reverse proxy server to support Sametime<br />

When a Sametime server is deployed behind a reverse proxy server, the<br />

administrator must configure mapping rules on the reverse proxy server.<br />

These mapping rules enable the reverse proxy server to translate (or rewrite) a<br />

URL associated with the reverse proxy server to the URL of an internal<br />

Sametime server.<br />

When a user connects to a Sametime server through a reverse proxy server, the<br />

reverse proxy server must be configured with “mapping rules” to support the<br />

following actions that enable Sametime users to attend meetings and participate<br />

in chat sessions:<br />

► The user must be able to click on links in the Sametime server home page<br />

and navigate to the various HTML pages of the UI. This capability requires<br />

the reverse proxy server to rewrite the URLs of the HTML pages that<br />

comprise the Sametime User Interface.<br />

► The Sametime Java applet clients that load in a user's Web browser must be<br />

able to connect to the services on the Sametime server. Since these<br />

connections must occur through the reverse proxy server, the reverse proxy<br />

server must also be able to rewrite the URLs required to establish these Java<br />

applet connections to the services on the Sametime server.<br />

This section provides some guidelines on how mapping rules are configured on a<br />

reverse proxy server to accomplish the translation (or rewriting) of URLs when<br />

the reverse proxy operates with Sametime.<br />

Alias considerations and multiple servers<br />

Any reverse proxy server that operates with a Sametime server must support the<br />

affinity-id (or server alias) in URLs.<br />

For example, if the incoming URL from the Web browser is:<br />

http[s]://reverseproxy.ibm.com/st01/stcenter.nsf<br />

then the mapping rules on the reverse proxy server map the "st01" affinity-id to<br />

the Sametime server named "sametime.ibm.com" and the affinity-id ensures the<br />

reverse proxy server rewrites the incoming URL to:<br />

http[s]://sametime.ibm.com/stcenter.nsf<br />
