really, it's the client that decides whether the content should be encoded
or not, which they typically do by setting an Accept-Encoding request
header.  so remove that in the client and no compression.

from the server side, it looks like you can set use the subprocess_env table
to suppress it if you have access to the API

  apr_table_setn(r->subprocess_env, "no-gzip");

not sure if either of these suits you, though.
