I feel like just saying Web Isolation rewrites HTTP responses is about 
like saying you're going to experience moisture when standing in front 
of a tidal wave.  Is it true?  Yes.  Does it convey scope?  Not even 
remotely.

Aside:  I think the fact that Web Isolation uses JavaScript is ironic.

Ya....  It seems as if Web Isolation does a full render of the requested 
page in a sandbox / custom web browser hostsed on the Web Isolation 
infrastructure  and sends a responsive representation thereof to clients 
for use / interaction with.  This is all done in the context of an HTTP 
reqeust (over HTTP and / or HTTPS?) in a seemingly very transparent way.

This infrastructure to do the rendering and recomposition to generate 
and send the inew faximily to the client is WAY beyond what Squid is 
designed to do.

I agree that this probably could be done through content adaptation. 
But this seems like it is an entire product / industry unto itself.
