As I need to rewrite the response headers and body that were returned from another module in apache 1.3, I've tried to find the solutions over weeks and finally found that mod_gzip do the similiar job. In "The handling of modules by Apache 1.3" section of mod_gzip installation web page (http://schroepl.net/projekte/mod_gzip/install.htm), it mentioned that it has done something contradict with apache 1.3 so that it can read the response from another module. After go through the mod_gzip.c, I still can't understand the technique that acheive this. Then I have read the books "Apache, the definitive guide" & "writing apache modules in perl & C", both of them don't mention this technique. Can someone has more details on this?
