Apache caches the server_rec, so as Stas said, modifying it affects things globally, and across the request. In C, if I wanted to local'ize the server_rec for the request, I would make a copy of the server_rec, store it in r->server, and then modify its contents (top-level only) through r->server. Stas: is there a way to do this in mod_perl? What do you think of local'izing the server_rec when an application attempts to make request-specific changes? There would need to be a clear API for making request-specific or global changes. (Changes through r->server instead of directly through the global server rec, e.g. in the main httpd.conf) Maybe pass $r as an arg to the server_rec method if you want it local'ized? Just musing ...
