A method includes the step of establishing a collaboration session between a first client and a second client. A requested resource is cached with the session host in response to a request having a first uniform resource locator (URL) issued by the first client, if the requested resource is a pre-determined type of resource. A second URL is provided to the second client. The second URL identifies the requested resource or the cached resource in accordance with whether the requested resource is cached. Apparatus for enabling collaboration includes a web server, a cache, and a filter. The web server provides a requested web page in response to a first client'"'"'s request. The filter stores the requested web page in the cache, if the requested web page is a pre-determined type of web page.

In one embodiment, the requested resource is cached if it is a dynamic web page. In one embodiment an expiration date of the requested resource determines whether the requested resource should be cached.
