CSS & CE 507 Reverse Proxy Cacheing

I am trying to set up a CSS and CE507 to perform reverse proxy cacheing. I can not get the Cache to respond back. The link on CCO is way old and doesn't offer any helpful information. I pretty confident on the CSS config, my trouble is with the CE. The CE is on a different L3 network than the origin server. The CSS & the CE are located behind an Internet PIX. I've set the CSS service for proxy and I've set my 4.1 ACNS CE to use proxy for my associated domains. Please help..........,

Re: CSS & CE 507 Reverse Proxy Cacheing

Take a look at the following Tech-tip that I wrote:

In order for this to work you need to configure the service as a type transparent-cache and ensure that you have 'no cache-bypass' configured as well. On the Cache, you need to ensure that you have 'http l4-switch enable' and either an http outgoing proxy statement that

points to the webserver's VIP (in my example the cache_request_rule) or a rule that does the same.
