Hi Folks,

I'm a noob with mod_rewrite, and my logging has wondering about some things. (BTW, I'm on 2.2)

Here's the request command, the virtual host's rewrite rule, and the generated log output: http://apaste.info/5ga

I don't really understand why the logs are showing me an exhaustive list of the files that are *included* by the requested (dynamic) script. Is it normal? Is it something I need to configure to go away? I thought the NS flag would make those go away, but obviously I don't really understand NS or subrequests. (I *think* I understand PT, but I'm not sure.) I've read http://httpd.apache.org/docs/2.2/rewrite/flags.html a bunch of times, but I still don't completely get what NS does, given it doesn't do what I thought it did(?).

Also, the existence of the NS flag, and the fact that the rewrite log is showing subrequests to me makes me wonder A) why httpd deals with subrequests, when it seems like an application server concern and B) what use there might be in having httpd process subrequests; what's a use case for that?

Thanks,
Jamie
