Depending on what you are trying to do, either phase handlers or
request body filters might work for you.

If they won't, you are probably looking for either proxy-level
modifications with proxy module configuration options (such as
proxy_set_header and proxy_set_body), or for a proxy-like module
which will do appropriate modifications.
