My hope (and expectation) is that I can get apache to do the gzipping. I'm 
quite sure it is Apache that is gzipping the output. 

I've got mod_deflate loaded and put the following two directives in 
httpd.conf:

AddOutputFilterByType DEFLATE text/xml
SetInputFilter DEFLATE

(It appears that for gzipping to be applied to input, it must be all or 
nothing, but the docs seem to say that Apache will only ungzip those 
requests carrying a header of Content-Encoding: gzip).  For my money, I 
can't determine if the SetInputFilter directive is doing anything or not. 
Adding a 'LogLevel debug' doesn't provide any more information.

I enabled some zidestore relevant debugging options (?
SoDebugObjectTraversal? and ?SoRendererDebugEnabled?) and now I get this 
in the /ogo-zidestore-1.5-err.log:

I am wondering if the 'so-dflt-renderer' actually has anything to do with 
it. 

Thanks,
Bernard
