public class KeepOnServerEditor

extends HttpEditor

Keep On Server Editor Edit the links on a page so they go through the server. This is useful if WBI is running in server mode rather than in proxy mode. "Proxy mode" means that the web browser is configured to use WBI as an HTTP proxy. In proxy mode, every HTTP transaction goes through WBI, regardless of the URL. "Server mode" means the web browser is not configured to use WBI as a proxy, and rather makes requests to the WBI as it would any other web server. It is possible for WBI to act just as a web server in this mode, but it is also possible to tunnel requests to another server, and rewrite the links to make them look like they came from the WBI server, to make the client "keep on the WBI server". For example, a link to http://www.ibm.com might be rewritten to http://my.wbi.server/tunnel?url=http://www.ibm.com. To accomplish the affect of using WBI in "server mode", it is necessary to handle redirects and error conditions properly, and to actually edit the links in the document. This bean uses a LinkProcessor to rewrite the links. The LinkProcessor is generic, and itself turn relies on an implementation LinkRewriter to enumerate the policies of how links should be rewritten.
