Aha. Excuse my ignorance but would that also work in a setup like this?
Client

|
|---------| mod_cache (unhacked)
| Reverse | mod_headers
| Proxy | mod_proxy
|---------|
|
|
|-------------|
| propriatary |
| backend |
| HTTP server |

Is the module order in the request cycle such that the header would
be added before mod_cache takes a look at them? Well, I guess I could
experiment to find out but it'd be nice to get an insight answer from
an expert.
