Use of suffix in generating key when using CacheFilter

Hi guys,

I've got a small issue with the CacheFilter class.

I'm trying to extend the CacheFilter whereby i can do some pre-caching
operations.
What i want to do is apply a network filter before calling the cache filter,
which will tell me which customer base i'm dealing with (via ip address
matching), and then add a suffix to the cache key generated, therefore
caching different results per customer base.

In ServletCacheAdministrator there is a possibility to pass a suffix
parameter when generating a key, so it would be nice if possible that the
CacheFilter had a mechanism in place to pass in a suffix (e.g. have a method
doFilter(javax.servlet.ServletRequest request, javax.servlet.ServletResponse
response, javax.servlet.FilterChain chain, String suffix)).

Any possibility this could be done?
chico.

There's a nasty looking line of code in the
CacheHttpServletResponseWrapper.getWriter() method:

cachedWriter = new PrintWriter(getOutputStream());

This causes the PrintWriter to use the default character encoding, which
I suspect is at least part of the problem...  I won't get time to tackle
this for at least a week, so if someone else wants to have a go at it in
the meantime please feel free :-)
