Hi all. I did some search on the web and the archives here and did not find an conclusive answer to this question.

Apache has both input a filters (work on the request before content generation) and output filters (work on generated content). As I am exploring the possibility to port some Apache modules that transform data in both directions in a proxy-setup to Nginx, I am wondering whether Nginx has input filters as well. What I have read about Nginx modules seem to indicate that it does not. Is that correct?

I am aware that I could hack something into the proxy module, but I would like to avoid that approach.

Thanks for any insights or pointers.
