URL rewriting and internal links on Apache

I have a 2.2 Apache with the weblogic plugin enabled, which it simply redirects all the requests to the application server. Basically, when I call the page http://myip/blabla/home.page , it is a page resident on the application server. What I need to do is to understand how to perform a couple of things: 1. When I ask for http://myip/home.page the Apache should give me the http://myip/blabla/home.page . 2. The internal links of the home.page should be with the "blabla" removed. 3. When I click on the modified link, the page served should be the http://myip/blabla/linked.page but with the URL rewritten like this: http://myip/linked.page
