Realized this was a Tomcat exsample filter.

I think that the Compression servlet is a valuable contribution.
It can be enabled as a global filter for the Cocoon Servlet.

In addition to URL namespaces, compression is best controlled in combination 
with MIME types.
According to Apache mod_deflate, browsers are not always good at handling 
compression for non html content.
Therefore the servlet should be improved to accept a compress-mime-types.txt 
file with a list of mime types which can be compressed. 

For example:

# MIME types that can be compressed 
text/css			
text/directory
text/enriched
text/html			
text/parityfec
text/plain			
...


Other compression filters are publicly available as well:
